Claim Text:
1. A driver circuit for generating a reset pulse of an output waveform, said driver circuit comprising: a plurality of ramp paths, each ramp path having a different resistance to vary a current provided to a gate of a transistor to control a slope of said reset pulse such that said reset pulse has a desired slope amongst multiple selectable slopes; a falling switch configured to selectively connect said gate of said transistor to ground, thereby selectively holding said output waveform low; a mode switch configured to selectively connect said plurality of ramp paths to said gate and said falling switch; a switch controller configured to selectively enable said plurality of ramp paths and said falling switch to generate said reset pulse, wherein selectively enabling said plurality of ramp paths selects said desired slope from said multiple selectable slopes.
