Abstract: Disclosed is an energy mixer having a first active diode coupled between a first input node and an output node, and a second active diode coupled between a second input node and the output node. A first capacitor is coupled between the first input node and a dynamic node, and a second capacitor is coupled between the second input node and a third node. Switching circuitry is configured to selectively couple the dynamic node between a fixed voltage node and the second input node in response to a control signal provided by control circuitry. When an output voltage at the output node is within a first range, the dynamic node is coupled to the fixed voltage node and when the output voltage is within a lower voltage second range, the dynamic node is coupled to the second input node such that first capacitor and second capacitor are coupled in series.

Abstract: A switched capacitor DC-DC converter, which includes a pulse frequency modulation circuit, a multiplexing pulse-width modulation circuit, and a switched capacitive element, is disclosed. The switched capacitive element is coupled between the pulse frequency modulation circuit and the multiplexing pulse-width modulation circuit. The pulse frequency modulation circuit uses a DC source signal to charge the switched capacitive element. The pulse frequency modulation circuit provides a group of output signals by multiplexing the switched capacitive element and reduces reverse current to the switched capacitive element when updating each of the group of output signals.
