Abstract: An apparatus includes: a switched capacitor (SC) converter to generate a first voltage based on a voltage source; and a direct current-to-direct current (DC-DC) converter to generate a second voltage based on the voltage source of the apparatus. A difference between the first voltage and the second voltage corresponds to an output voltage.

Abstract: A switched capacitor array circuit for use in a voltage regulator, including L, M and N banks of capacitor positions disposed intermediate an input node and a ground node, between the input and output nodes and between the output node and the ground node, respectively. Switching circuitry operates to switch three capacitors between a common phase configuration and a gain phase configuration. Two of the capacitors are disposed in one of the L, M and N banks of capacitor positions, with the third capacitor being disposed in a different one of the L, M and N banks of capacitor positions in the common phase configuration. When switched from the common phase to the gain phase configuration, at least one of the three capacitors is moved to a different capacitor position.

Abstract: A switched capacitor array circuit and method, with the array circuit being coupled between an input node and an output node and which is capable of providing multiple gain states. The array circuit includes an L band of capacitor positions disposed between the input node and a third node, typically the circuit common, an M bank of capacitor positions coupled between the input and output nodes and an N bank of capacitor positions coupled between the output node and the third node. Each of the L, M and N banks of capacitor positions includes series and parallel capacitor positions. In one embodiment, the array includes first, second and third capacitors together with switching circuitry and control circuitry. The control circuitry causes the switching circuitry to switch the array circuit between a common phase configuration and a gain phase configuration so as to provide a gain state value Gsc.

Abstract: A switched capacitor circuit, for use in voltage converters and the like, which includes a switched capacitor array, a plurality of MOS transistor switches and drive circuitry for controlling the state of the switches. The drive circuitry alternates between a first phase where at least one capacitor of the array is connected by the switches between an input node and an output node and a second phase where the capacitor is connected in series between one of the output and input nodes and a third node, such as a circuit common. Boost and buck gain configurations are achieved when connected to the output and input nodes, respectively. A voltage management feature is implemented to control voltages produced in the array so that no PN junction of the transistor switches formed by a body and the drain/source regions disposed in the body becomes forward biased.
