  • 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.

  • Patent number: 9306844
    Abstract: A router includes a plurality of virtual networks, a plurality of output links, at least one decoder and arbitration circuitry. Each virtual network has a plurality of virtual network inputs and a plurality of virtual network outputs. Each virtual network output is associated with an output link. The decoder decodes a header of a data unit received on a virtual network of one of the virtual network inputs. The decoder generates a first request and a second request. The first request is for the allocation of a virtual network output of the virtual network to the virtual network input. The second request is for the allocation of an output link associated with the virtual network output to the virtual network output. The arbitration circuitry performs arbitration of the first request and arbitration of the second request in parallel.

  • 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.
