An adiabatic logic is a technique to design low power digital VLSI's. This paper describes the design and VLSI implementation of a multiplier using a two phase drive adiabatic dynamic CMOS logic (2PADCL) circuit. Circuit operation and performance have been evaluated using a 44-bit 2PADCL multiplier fabricated in a 1.2 µm CMOS process. The experimental results show that the multiplier was operated with clock frequencies 800 kHz. The total power dissipation of the 44-bit 2PADCL multiplier was also 5.19 mW at the 1.5 V DC power supply voltage.
