Abstract :
This paper demonstrates the low-energy operation of a two-phase clocked adiabatic static CMOS logic (2PASCL) on the basis of the results obtained in the simulation of a 4-bit ripple-carry adder (RCA) and D-flipflop employing 2PASCL circuit technology. Two-phase unsymmetrical power supply clocks are introduced to increase the logic transition level. Energy dissipation in the unsymmetrical clocked 2PASCL RCA and D-flipflop are 77.2% and 55.5% less than that in a static CMOS at transition frequencies of 10-100 MHz respectively.
