ABSTRACT:
A variable transition time generator has a differential emitter follower circuit that has a push-pull signal at the inputs for driving each end of a timing capacitor. An independently variable timing current source is coupled to each end of the timing capacitor. A differential buffer amplifier passes the voltage across the timing capacitor to an output. A d.c. compensation circuit has a statically biased emitter follower pair of transistors that are driven independently by a pair of variable compensation current sources that track the independently variable timing current sources, the output of which is combined with the output of the buffer amplifier. Also combined with the output of the buffer amplifier is a step correction output derived from the differential input signal. The result is a high speed variable transition time generator that simultaneously produces independently controllable opposite polarity transitions.
