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.

Circuits and methods for measuring the output current of a switched capacitor regulator

Circuits for a voltage regulator are provided, comprising: an inductor having a first side coupled to an input voltage; a first flying capacitor; a second flying capacitor; and a plurality of switches, wherein: in a first state, the plurality of switches couple: a second side of the inductor to a second side of the first flying capacitor and an output node; a first side of the first flying capacitor to a first side of the second flying capacitor; and a second side of the second flying capacitor to a voltage supply, in a second state, the plurality of switches couple: the second side of the inductor to the first side of the second flying capacitor; the second side of the second flying capacitor to the output node and the first side of the first flying capacitor; and the second side of the first flying capacitor to the voltage supply.

Circuits and methods for hybrid 3:1 voltage regulators

This application relates to methods and apparatus for DC voltage conversion. A DC converter () is described, with a charge pump circuit comprising a plurality of charge pump stages (--) each charge pump stage comprising connections for respective first and second capacitors for that stage (CA, CB; CA, CB; CA, CB). The charge pump also has a switch network, wherein the switch network comprises, between each successive stage, four switching paths (SAA, SAB, SBa, SBB; SAA, SAB, SBa, SBB) for separately connecting a respective first electrode of each of the first and second capacitors of one stage to a first electrode either of the first and second capacitors of the preceding stage, so that the relevant capacitor of the one stage can be charged by the relevant capacitor of the preceding stage.
