  • Methods and apparatuses for power control during backscatter modulation in wireless power receivers
    Patent number: 9929568
    Abstract: A wireless power enabled apparatus including a wireless power receiver. The wireless power receiver includes a receive coil configured to generate an AC power signal responsive to a wireless power signal. A rectifier is configured to receive the AC power signal and generate a DC rectified power signal. A power transistor in a pass-transistor configuration is configured to receive the DC rectified power signal and generate an output power signal. A compensation current source operably coupled to the output power signal is configured to maintain a substantially constant voltage on the output power signal by adjusting a current through the compensation current source during a communication period employing backscatter modulation on the receive coil.

  • No load to high load recovery time in ultraportable DC-DC converters
    Patent number: 7385379
    Abstract: A voltage converter that recovers quickly from a transition from a power save mode where the load is relatively low to a fully operation mode where the load is relatively high. The converter utilizes circuitry that is not dependent upon the slew rate of an amplifier in recovering from the transition. When the transition is sensed high current is applied for a short duration to increase the output voltage rapidly and thereby shorten the transition time from power save mode to fully operational mode.
