Abstract :
A special waveform to replace the power supply of a modified D-latch is presented. The power supply only exists when it is needed. Hence, the amount of switching at certain nodes is reduced. Furthermore, the voltage ramp in the power supply waveform enables energy recovery. HSPICE simulations show that the power consumption has been reduced by between 11.4 and 64.2%
