ABSTRACT:
A high speed transistor switching circuit includes an inductor connected in the transistor base lead for reducing the switch-off time of the transistor. A controllable switch, e.g. a second transistor, is connected in parallel with the inductor for briefly short-circuiting the inductor when the first transistor is switched on thereby reducing the transistor switch-on time.
