Abstract
A bootstrap condenser connected to the output of the circuit is preloaded during the low output state when the load transistor is off and the drive transistor is normally on. A commutation signal brings about extinction of the drive transistor and connection of the condenser to the gate of the load transistor to turn on the latter and secure the resulting rise of the circuit output. Transistors of the pilot circuit are arranged for maximum bootstrap efficiency.
