摘要:
A circuit includes an amplifier output stage that includes a high switch and a low switch that generates a pulse width modulated (PWM) output signal to provide a load current to a load in response to a PWM input signal. The circuit includes a high gate drive that drives the high switch with a PWM high drive signal derived from the PWM input signal. This includes a low gate drive that drives the low switch with a PWM low drive signal derived from the PWM input signal. The circuit includes an edge corrector that adjusts at least one of a leading edge and a trailing edge of the PWM input signal to compensate for response time differences with respect to a direction of the load current to the load.
