Abstract: A voltage regulator has a slow loop for providing a regulated DC current and a fast loop for providing a transient current. Feedback information is used to monitor the output voltage and control the current used to generate the output voltage. The voltage regulator does not need a capacitor to create transient current.

Abstract: A digitally-assisted voltage regulator includes a gate driver circuit and a compensation circuit. The voltage regulator digitizes the load profile, and uses the digital information to compensate for process and temperature variations. The voltage regulator outputs a regulated voltage signal and one or more control signals based on a supply voltage and a reference voltage. The gate driver circuit receives the regulated voltage signal and generates a gate driver signal. The compensation circuit receives the control signal and generates first and second compensation signals. The voltage regulator regulates a voltage level of the regulated voltage signal using the regulator compensation signal, and controls a ramp-rate of the gate driver signal using the second compensation signal.

Abstract: Disclosed is a differential driver circuit including an input module to receive an input signal and split the input signal into high and low components, a first level shifter to receive the high signal component and output a high side input signal to a high side driver, a delay module to receive the low signal component and output a low side input signal to a low side driver, and a multi-voltage domain phase detector to measure a phase difference between the high side input signal and the low side input signal to provide feedback to the input module and output a phase adjusted output signal to match a first delay timing of the first level shifter.
