Abstract
A Local Dynamic Power Controller (LDPC) generates and deliver to a load a full swing voltage supply signal and a reduced swing voltage supply signal. Both the full and reduce voltage supply signals are generated from a single power supply. The full swing voltage supply signal is supplied when the load is in full operational mode whereas the reduce voltage supply signal is provided when the load is in a sleep mode. As a consequence, power dissipated in the load is reduced.
