ABSTRACT:
A circuit for improving the rise time of an electronic signal including a voltage generator for generating a reference voltage, a comparator for comparing the voltage of an electronic signal whose rise time is to be improved with the voltage of the reference voltage generator, and a current pulse generator controlled by the comparator for generating a current pulse of a predetermined duration responsive to the comparison of the comparator. The current pulse is of sufficient magnitude to assist the rise time of the electronic signal.
