Pass-transistor adiabatic logic using single power-clock supply

We present a new pass-transistor adiabatic logic (PAL) that operates from a single power-clock supply and outperforms the previously reported adiabatic logic techniques in terms of its energy use. PAL is a dual-rail logic with relatively low gate complexity: a PAL gate consists of true and complementary NMOS functional blocks, and a pair of cross-coupled PMOS devices. In simulation tests using a standard 1.2 /spl mu/ CMOS technology, the circuit has been found to operate up to 160 MHz clock frequency and down to 1.5 V peak-to-peak sinusoidal power-clock supply. Operation of a 1600-stage PAL shift register fabricated in the 1.2 /spl mu/ CMOS technology has been experimentally verified.
