Abstract
The present disclosure discloses methods and circuits to reduce power consumption of switching circuits comprising two or more units by applying charge sharing/reuse of capacitive loads between the units. The units are stacked in a way that, if an output potential of a unit is to be lowered and an output potential of a neighboring unit is to be lifted, a charge of the unit to be lowered is reused by transferring it to the unit to be lifted depending on input signals of the units. In case of input signals having an arbitrary relationship a storage unit is placed at a junction of two neighboring units to store the charge temporarily until a neighboring unit is to be lifted.
