Abstract: The present disclosure shows a reconfigurable Dickson Star SC regulator that can support multiple conversion ratios by reconfiguring between various modes. The reconfigurable Dickson Star SC regulator is designed to reduce the number of redundant capacitors by reusing capacitors and switches across multiple modes of operation (across multiple conversion ratios). The present disclosure also shows a hybrid (e.g., two-stage) voltage regulator.

Abstract: Circuits comprising: a capacitor; switches that, when State0, couple the capacitor in parallel with the load and, when State1, couple the capacitor in series with the load, wherein a first of the switches connects the capacitor to ground when in State0 and wherein a second of the switches connects the capacitor to an input voltage when in State1; a third switch, wherein a first side of the third switch is connected to the capacitor identically to one of the first switch and the second switch (OFWSW), wherein the third switch switches identically to the OFWSW, wherein the third switch is smaller than the OFWSW; a first resistor connected to the second side of the third switch; and a hardware processor that measures a current flowing through the first resistor and estimates the current provided to the load based on the current measured as flowing through the first resistor.
