  • Patent number: 11967596
    Abstract: An integrated circuit includes a first-voltage power rail and a second-voltage power rail in a first connection layer, and includes a first-voltage underlayer power rail and a second-voltage underlayer power rail below the first connection layer. Each of the first-voltage and second-voltage power rails extends in a second direction that is perpendicular to a first direction. Each of the first-voltage and second-voltage underlayer power rails extends in the first direction. The integrated circuit includes a first via-connector connecting the first-voltage power rail with the first-voltage underlayer power rail, and a second via-connector connecting the second-voltage power rail with the second-voltage underlayer power rail.

  • Patent number: 10199944
    Abstract: System and method for regulating a power converter. The system includes a comparator configured to receive a first signal and a second signal and generate a comparison signal based on at least information associated with the first signal and the second signal. The first signal is associated with at least an output current of a power converter. Additionally, the system includes a pulse-width-modulation generator configured to receive at least the comparison signal and generate a modulation signal based on at least information associated with the comparison signal, and a driver component configured to receive the modulation signal and output a drive signal to a switch to adjust a primary current flowing through a primary winding of the power converter. The modulation signal is associated with a modulation frequency corresponding to a modulation period.
