  • Low-power feedback and method for DC-DC converters and voltage regulators for energy harvesters
    Patent number: 8222881
    Abstract: A converter (10) for converting a first DC voltage (VDD) to a second DC voltage (VOUT) includes an output stage (40) for producing the second DC voltage (VOUT) in response to both the first DC voltage (VDD) and an output of an error amplifier (20). A sampling circuit (15) periodically energizes a voltage divider (R0,R1) by periodically coupling a first terminal thereof to the second DC voltage and periodically coupling an output (14) of the energized voltage divider to a feedback conductor (7) to refresh a feed back capacitor (C0) coupled between the second DC voltage and the feedback conductor. The feedback conductor is coupled to an input of the error amplifier.
