Abstract: Described is an apparatus having a non-linear control to manage power supply droop at an output of a voltage regulator. The apparatus comprises: a first inductor for coupling to a load; a capacitor, coupled to the first inductor, and for coupling to the load; a first high-side switch couple to the first inductor; a first low-side switch coupled to the first inductor; a bridge controller to control when to turn on and off the first high-side and first low-side switches; and a non-linear control (NLC) unit to monitor output voltage on the load, and to cause the bridge controller to turn on the first high-side switch and turn off the first low-side switch when a voltage droop is detected on the load.

Abstract: Described herein is an apparatus and system for generating a signal with phase angle configuration. The apparatus comprises an array of switch-resistors, each switch resistor to receive a control signal, wherein the array of switch-resistors to generate an output signal; and a circuit to configure phase angle of the output signal. The apparatus can be used for different package and inductor configurations. The apparatus provides flexibility to mitigate switching noise by adjusting phase angles, and provides the ability to enable and disable switch-resistors on the fly without ripples. The apparatus also saves power consumption by selectively turning off switch-resistors when phases are disabled. The output signal of the apparatus has smooth triangular waveforms for improving the quality of power supply generated using the output signal. Overall, the apparatus exhibits reduced sensitivity to process variations compared to traditional signal generators.
