Synchronization of Class-C Oscillators—Revisited

Abstract

In this paper, the lock-in behaviour of a synchronized Class-C oscillator, i.e., the frequency response characteristics together with the stability criteria, has been studied. It has been established that the so-called mistifying effects of a Class-A oscillator, viz., hysteresis and jump phenomenon, are absent in such an oscillator. Dependence of the locking range and locking time on the time constant of the automatic biasing circuit has been examined. Experimental results are also presented in support of the theoretical findings.
