摘要:
A digital linear voltage regulator includes a comparator, a finite state machine, and a current digital-to-analog converter (DAC). The comparator is preferably coupled to receive a reference voltage and an operating voltage supplied to a dynamic load. The comparator generates, during a clock cycle, a binary output based on a comparison between reference and operating voltages. The finite state machine (FSM) is coupled to receive at least one control signal that indicates a target operating state for the digital linear voltage regulator. The FSM receives the binary output from the comparator and generates a digital word, during a clock cycle, based on the target operating state of the digital linear voltage regulator and on the binary output. The current DAC is coupled to the FSM, receives the digital word and delivers current at the desired voltage to the dynamic load.
