Abstract: A DC-DC converter includes a plurality of switches configured to be in a first charging mode until current through an inductor reaches a first current threshold to thereby indicate an end of the first charging mode. Responsive to the end of the first charging mode the DC-DC converter is configured to operate in a second charging mode for a time period ΔT in which a first side of the inductor is coupled to an input voltage and a second side of the inductor is coupled to a load. Responsive to the end of the time period ΔT, the DC-DC converter operates in a discharge mode until current through the inductor reaches its minimum.

Abstract: A method includes selectively coupling first and second input nodes of a capacitive bridge to first and second voltages, respectively, and selectively coupling first and second output nodes of the capacitive bridge to first and second output terminals, respectively, during a first phase of a clock cycle. The method further includes selectively coupling the first and second input nodes to the second and first voltages, respectively, and selectively coupling the first and second output nodes to the second and first output terminals, respectively, during a second phase of the clock cycle.

Abstract: An integrator circuit includes a switched capacitor bridge including first and second inputs and first and second outputs. The switched capacitor bridge is configured to sample first and second reference voltages twice per unit time interval. The integrator circuit further includes an integrator coupled to the first and second outputs and configured to integrate charge dumped into the first and second outputs twice per unit time interval.
