AbstractA method and system for reducing power consumption in digital circuits using charge redistribution include a plurality of signal lines, an intermediate floating virtual source/sink, and a charge redistribution circuit connected to each signal line that isolates the signal line from its source and connects it to the intermediate floating virtual source/sink during an idle period prior to a change of state.This charge redistribution provides steady state statistical independent advantage due to charge recycling without inserting extra complimentary lines.
