Certain Microchip (was Atmel) ATtiny and ATmega microcontrollers have a handy phase-locked loop which boosts the 16MHz clock up to 64MHz for peripherals including the PWM. These tend to have a dead-band generator to provide a pair of non-overlapping but anti-phase PWM signals to drive a half-bridge power stage – the dead-band generator ensuring that …
