| Abstract: | By analyzing the power dissipation of the traditional static CMOS circuit adopted DC-supply and the energy-recovery CMOS circuit adopted AC-supply,from the point of energy dissipation of power-supply,this paper presented two sim ple power estim ation m ethods based on the PSPICE simulation of CMOS unit circuit.They were applied into the power estimation of two concrete circuits, the results intuitively reflect the switching activities and the power characteristics of the circuits. |
