Abstract

PURPOSE:To carry out the input limitation by detecting the forward bias state between the base and collector of the amplifier transistor which is saturated at the time of overinput. CONSTITUTION:The output of transistor Q2 is saturated at the time of overinput, and the forward bias is secured between the base and collector. As a result, detection transistor Q3 is turned on to turn on input limiter transistor Q4, and thus the overinput is offset to perform the limiter action. The limiter action is based on the threshold level between the base and the emitter of Q3, and also can limit the minor input because of intervention of the amplification step.
