Abstract
A novel FET switching circuit including a high beta transistor in an analog switch FET circuit for rapid, low power consumption with transient current pull up to the FET switching circuit to the on condition. A novel circuit is utilized and coupled to the transistor for the derivation of a reference voltage for the turn off of the analog switch FET. A novel transistor - JFET nonsaturating switching circuit which gives high speed turn off is incorporated.
