Oscillation Circuit With Odd
Seriya matematiki, mekhaniki,
Nr 4o pp 123-129 (USSR)
ABSTRACT: The oscillation circuit shown by figure 1 with nonlinear inductance
without field magnetization is analyzed. It is investigated whether
even harmonics exist in this circuit. The method of successive
approximation is applied which considers any degree of smallness.
The differential equation (1) is the equation for the forced
oscillation generated by a sinuaoidal voltage applied to the
oscillation circuit. Under consideration of the dependence between
the magnetic flux and the current according to formula (1), and by
introduction of the quantities (3), the differential equation (4)
is obtained from differentia3, equation (1) by differentiating with
respect to time; the solution of (4) is found by the series formula
(5). It is shown for the resonance case that no even hnr-onics
appear either at the same order of smallness of nonlinearity and
attenuation or at different orders with any approximation. The same
results are obtained if the relation coo -- kti(k - 2,39 ... ) holds

TITLE: Some General Properties of nonlinear Roactive Elements
PERIODICAL: Uspekhi fizicheakikh nauk, 1959, Vol 69, Nr 2, pp 217-267
(USSR)
ABSTRACT: The present very detailed paper in nearly text-book-like form
gives a survey of the properties and the possibilities of ap-
plying nonlinear reactive elements in the field of electronics.
In the introduction the fundamental basic concepts used are
formulated, and a number of definitions is given in a very
illustrative form (nonlinearity of the volt-amp6re characteris-
tic of the element (Figs 1,2,3); capacitance, resistance,
modulation; discussion of various basic circuits; it is shown
that, with a purely reactive element, also if it is nonlinear,
it is not possible to obtain direct current from alternating
current, and that it is also impossible to transform direct
current into alternating current by a system consisting of any
combination of nonlinear reactive elements and constant re-
sistanoea). Chapter 2 deals with the general energy relations
Card 1/4 of nonlinear reactive elements. In this chapter the application

of nonlinear reactive elements as modulators in magnetic and
dielectric devices is discussed, and several special problems
of modulation are theoretically explained. Chapter 3 deals
with the analysis of reactive modulators by the method of the
small signal. The description is taken essentially from western
publications (Refs 13-16). Theoretical considerations are ap-
plied to the example of a two-circuit reactive modulator
(Fig 15). Further, a non-reversing modulator with summation of
the combination frequencyc,) 2 - ro) + (,~ is discussed, and also a
reversing modulator for which (_12 = c3o - 01 holds. The theory of
these two circuits is given and discussed. In the following, a
parametric amplifier with negative input conductivity (Fig 17)
As theoretically dealt with, as also the noises of an-amplifier
with negative conductivity; ~,i shown by analysis, the total
output noise may be conaideTed to be additively composed of
8 components. Chapter 4 deals with the investigation of the
form of nonlinear capacitance in a crystal diode in p-n transi-
tion, and � 5 mentions some new possibilities of applying non-
Card 2/4 linear reactive elements, partly taken from the periodical PIRE

(June 1958) and partly from other western publications. The
following is dealt with in detail: A reactive wide-band
amplifier with low noise level (block scheme figure 27), the
experimental characteristics of a microwave parametric ampli-
fier on a semiconductor diode (Fig 28), the measurement of
the noise faczor of two types of amplifiers with pulsating
reactivity in which semiconductor diodes are used (Figs 29,30).
In this connection the lectures by V. S. Etkin and Ye. M.
Gershenzon'which were held at the third All-Union Conference
of the MVO SSSR on radioelectronicB (Kiyev, January 23, 1959)
were mentioned, who work at the laboratory of Professor
N. N. Malov at the Moskovskiy gosudarstvennyy pedagogicheskiy

pagates in the conductor as a symmetric surface wave with a field struc-
ture-that is equal to that in the coaxial cable, and is shown in Fig. 2.
The HY -component of the magnetic field is determined by means of a frame
antenna with a detector and a galvanometer. The following may be demon-
strated by means of this device: The equivalence of the displacement

the frequency characteristic of the amplifier is represented by the pro-

dealt with a low-frequenoy parametric transformer with circuit frequencies
of about 100 and 400 ke/see. In conformity with Eq. (2)y the transition
processes had two constant timesq and pulsations in the transition Pro-
oesses were observed in the case of mietuning. Further, it was found that
the duration of the transition prooesav in the case of large K, was pro-
portional to K (K being the voltage amplification factor in the first air-
ouit of a regenerative transformer)* The duration of the transition pro-
oess was the time during which the oscillation amplitude attained the
(I - e-1)-fold of its steady value. In a non-rotating modulatorp the du-
ration of the transition process dropped monotonically with increasing k2
in both circuits. The time of formation In the second circuit was slightly
longer than in the first one due to a slow increase of oscillations in the
second circuit at the beginning of the formation process. There are 6

Double-tuned parametric oscillator with external feed
PERIODICAL: Moscow Universitet. Vestnik. Seriya III. Fizika,
astronomiya, no. 6, 1961, 3 - 11
TEXT: A double-tuned parametric amplifier operates as an oscillator if
the feed amplitude is high enough. A self-excited oscillator whose
amplitude is limited by a non-linear resistor in one of its circuits is
considered. Synchronization of the oscillator with an external force is
also dealt with. In experimental investigations, the authors used a
parametric oscillator with frequencies of 100 and 400 kcps in the two
circuits, with semioonduoting diodes of the types AF'U,-27 (DGTo-27) and
A809 (D809) serving as nonlinear capacity, It was found that the
amplitude is limited either by a nonlinear resistance or by a dependence
of the parametric connection between the circuits on amplitude fluctua-
tions. Perturbations that are due to the nonlinear reactance lead to a

TEXTt In the design of parametric amplifiers with a non-linear re-

shown in Fig. 1b, the conductance gp is normally neglected at high
frequencies, if the diode is strongly back based, so that losses in
the diode are 'determined mostly by series base resistance RB. This
is not always correct. At high frequencies, the base resistance Rs
and the p-n junction capacitance practically do not vary with fre-
quency, while as determined from the experiment losses in the p-n
junction they are frequency dependent and in order to approximate
X
them R-s has to be made variable. At very high frequencies, the di-
electric losses of the semi-conductor ake added,.Jo the losses of
the base conductance. These los-ses are quenoomependent and con-
centrate in the region of the epletion gion 6f the p-n junction
and should, therefore, be rep ente"a as a conduction, which de-
pends on frequency'and on thefnetion-bapacitance. In the present
article, the author derives general equations for a double contour

form additional resonant Circuits at frequencies for which the am-

TITLE: Experimental investigation of a microwave three-cir-

PERIODICAL: Radiotekhnika i elektronika, V.-71 no. 7, 1962,
1152-1156
TEXT: The paper is concerned with a parametric converter which
can produce both the sum and difference frequencies. The converter
circuit is described in detail. The signal circuit is of,the co-
axial type which is protected by a choke against*the field of
other frequencies. In the experiments the signal frequency is 930
Mc/s and the pumping frequency.8330 Mc/s. Conversion gain inefea-
see with increasing pumping power and with increasing coupling to
the difference frequency circuit. Noise figure has a minimum at a
certain pumping power and decreases if the diode is cooled. Band-
width d6creaaes with increasing gain. It is also found, in accord-
_.ance with R, Do Weglein (Trans. I.R.E. PITT-8, 1960s 5), that the
Card 1/2

reverse current of the diode significantly increases the noise,
The main advantages of this converter are that it is insensitive
to load variation, has a relatively large gain, and the circuits
can be independently tuned. There are 7 figures.

degree of --park formation, but also on the quality df tile
brushes, to be able to clarify the character of spark
distribution and the origin of breakdown. The methods used at
present (Refs 1, 2, 3, 4) are listed. None of these methods
meetsthe requirements. The article contains a new method for
proved satisfactory in a
the study of comrmitation. The method
'
series of tests on machines ol different types. The method
consists of the following: the spark-formation indicator II-1
is connected to the working and the auxiliary brush. The
auxiliary brush is fixed on the heel of the working brush. The
indicator has one electron tube, on which the voltage
impulses between the brush and the commutator segments can be
observed. The indicator has a block in %'.hich all voltage
Card 1/2 impulses are added and averaged. The indicator instrument

connected to this block ind icates the averaged values of the
voltage impulses, i.e. they'.are.proportional to the.level of
the impulses and to their number in the time unit. This wiring
was recommended earlier by the authors,(Ref 5) for the tuning
of commutators. The great advantage of-the method is that the
Oscillograja permits not only the ~'&bserv-ation of the spark
distribution oft the commutator, bA also the cause of the spark
formation at each-segment. The article contains a series of
such oscillograms. There are 8'figures and 5 references, 4 of
which are Soviet.
