    摘要: An embodiment of the present invention comprises a voltage regulator including a droop compensation circuit and a voltage regulator circuit. The droop compensation circuit compensates for an output that changes over a period of time. This variable output may be the result of voltage regulator droop and/or a load transistor droop. For instance, the voltage regulator droop may be associated with the decrease in regulator output voltage that occurs during the course of applying a load. The load transistor droop may correspond to the decrease in RF transistor gain that occurs over the course of a transmit pulse. The variable output could be attributable to other phenomena. Moreover, the variable output that is compensated for is not necessarily decreasing over time, but, in fact, could be increasing over time, or could exhibit increases and decreases over time.

    摘要: A power regulator regulates the power provided to a transistor-based circuit, such as that which might be employed in a high stability MTI radar system. According to the invention, a variable reference voltage is controlled based on the frequency of operation. The output voltage of the power regulator is then modified accordingly. Preferably, the reference voltage is controlled based on the location of the target frequency in relation to the overall operational frequency band, which has been divided into a series of sub-bands.

    摘要: 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.
