  • Energy recovery system for droop compensation circuitry
    Patent number: 6677736
    Abstract: The invention comprises a voltage regulator including a droop compensation circuit and an energy recovery circuit. The droop compensation circuit adjusts the regulator output voltage to compensate for droop, such as voltage regulator droop, load transistor droop, or other variations to droop that occur in a load circuit over time. The droop compensation circuit compensates for voltage droop by providing an adjusted voltage input to the voltage regulator. The energy recovery circuit permits excess energy at the output of the voltage regulator to be transferred from the voltage output of the regulator to a voltage input of the regulator upon completion of a transmit gate during which the droop compensation circuit is operative. The energy recovery circuit can reduce heat generation and improve power efficiency and reliability.
