  • Power management for applications having duty-cycled high peak supply currents
    Patent number: 11557910
    Abstract: A method for power management for applications having duty-cycled high peak supply currents includes charging a buffer capacitor with a first current supplied by a battery, wherein the first current is limited by a current limiter. A load is supplied with a second current supplied by the buffer capacitor, wherein the second current comprises a pulsed current. The current limiter is controlled with at least one of a plurality of sensor inputs to limit a capacity degradation of the battery.
    Type: Grant

  • System for calibrating integrated circuit filters
    Patent number: 7257505
    Abstract: A main signal path filter is calibrated by calibrating a replica filter that tracks parametric changes in the main signal path filter. Programmed values of the replica filter determined during calibration are used to set programmed values in the main signal path filter. The main signal path filter signal does not need to be interrupted while calibration occurs. Power on testing of the main signal path filter and the replica filter can be performed to determine the parametric tracking relationship between the two filters.
