Abstract: A switched capacitor voltage regulator (SCVR) design, such as a continuous capacitive voltage regulator (C2VR) design, may use capacitors and switches to provide improved cost and space efficiencies. A remote sensing circuit may be used to improve C2VR performance. By adding a remote sensing circuit to the regulation feedback loop within the C2VR circuit design, the C2VR circuit may provide improved accuracy in voltage regulation, such as by providing a correction based on the voltage error between the remote-sensed voltage and the reference target. The remote sensing circuit may also provide transient information for under-voltage detection at an output terminal. This detected transient may become an alternating current (AC) portion of the under-voltage detection threshold, which improves the ability of the C2VR circuit to provide early detection for any under-voltage fault.
