ABSTRACT:
A Field Effect Transistor (FET) signal delay system with increased propagation delay time stability. This is accomplished by using a controlled voltage supply to power the amplifier stage. This voltage changes as the FET amplifier temperature increases in order to reduce the variation in propagation delay time, caused by the amplifier's gain and phase shift changes. By using this compensated amplifier as the delay element of a signal delay system, the propagation delay time stability is increased.
