Title: Bootstrap circuit

Abstract: A bootstrap circuit is disclosed which has capacitors, each connected between the base of a collector grounded transistor and the ground and between the emitter and the base of the same transistor and converts a rectangular input signal train into a sawtooth wave signal train. The bootstrap circuit is further provided with a switching circuit connected in series with the capacitor connected between the emitter and the base of the transistor and the switching circuit is opened when the supply of the rectangular input signal is stopped.
