Abstract

A method is developed of calculating the oscillation amplitude in simple valve oscillators of the regenerative type where grid-leak bias is used. The amplitude is found in terms of parameters which are functions of the valve and circuit constants, and the solution is presented in graphical form. Two types of amplitude instability are, studied and criteria for their existence deduced. The first type is periodic instability or squegging; the second type gives rise to the effect known as oscillation hysteresis. The analysis is applicable to all the common types of oscillator circuit subject to the condition that the valve should always operate in the space-charge-limited region.
