  • Publication number: 20170117795
    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.
