Driver with bulk switching MOS power transistor

摘要

A digital power supply system provides a supply voltage to semiconductor circuits. The power supply system utilizes a pulse width modulator to output a signal into a LC filter that generates a DC supply voltage. The width of the pulses output by the pulse width modulator are defined by an encoder that generates width information in response to a propagation delay detector that measures the propagation delay of a first clock signal when clocked by a second clock signal.
