Differential high voltage level shifter

摘要

A level-shift circuit translates a control signal to a level-shifted output. The level-shift circuit includes a pulse generator circuit for providing Set and Reset pulses based on the control signal and a level-shift circuit for translating the Set and Reset pulses to level-shifted Set and Reset pulses. First and second differential detectors are connected to monitor the level-shifted Set and Reset pulses to provide detection of communicated Set and Reset pulses despite the presence of transients in the level-shift circuit. A gate drive circuit employs the Set and Reset pulses communicated by the differential detectors to generate a gate drive signal.
