Abstract: A hybrid power supply circuit for supplying a power to a logic circuit performing a digital logic process and for controlling the charging/discharging of the logic circuit. The power supply circuit has an adiabatic power supply portion for charging/discharging the logic circuit in such a manner to suppress a sudden current change during initial time after the input signal changes, and a CMOS power supply portion for quickly charging/discharging the logic circuit to supply power level/ground level after the charging/discharging by the adiabatic power supply portion. The energy consumption of the circuit decreases even in a digital system having a plurality of logic circuits.
