Abstract: A method of controlling a switched capacitor voltage regulator includes modifying a topology factor associated with the switched capacitor voltage regulator in response to a change in output voltage associated with the switched capacitor voltage regulator, thereby maintaining an average output voltage associated with the switched capacitor voltage regulator. The method also includes modifying a loop delay associated with the switched capacitor voltage regulator in response to a change in operational frequency associated with the switched capacitor voltage regulator, thereby reducing ripple amplitude associated with the switched capacitor voltage regulator. A corresponding feedback/feed forward switched capacitor voltage regulator, controller, computer-readable medium, and voltage regulation system are also disclosed.

Abstract: A voltage comparator for comparing reference voltage applied to a first input node to an input voltage applied to a second input node. A first pair of transistors have output terminals coupled in series between the first input node and common node, and gate terminals connected together. A second pair of transistors, having both gate terminals of the pair connected to the gate terminals of the first pair of transistors, have output terminals coupled in series between a second input terminal, an intermediate node, and the common node. An inverter has an input coupled to the intermediate node and an output coupled to an output of the comparator. An optional feedback transistor might be used to latch the output of the comparator. Optional transistors might also be added to the first and second transistor pairs to selectively enable as the comparator and reset the latched output of the comparator.
