Abstract
A known FET driver circuit which is to be controlled at the gate by means of relatively low TTL signals, is improved in such a manner that the source potential of the input transistors is shifted oppositely to the input signal. This leads to an increase in the effective potential difference in the signal level applied to the input transistors and thus to an improved switching speed.
