This paper evaluates four designs of XOR employing our previously presented two-phase clocked adiabatic static CMOS logic (2PASCL) circuit techniques. 2PASCL XOR, which demonstrates the lowest power dissipation, is used for the 4 × 4-bit array 2PASCL multiplier. From our simulation results, at transition frequencies of 1 to 100 MHz, the 4 × 4-bit array 2PASCL multiplier shows a maximum of 55% reduction...
This paper investigates the possibility of using adiabatic logic as a countermeasure against power analysis attacks. As the examples of adiabatic logic styles, we evaluate single- and dual-rail gates that are driven a single sinusoidal power clock. From simulation results, we conclude that adiabatic logic countermeasures, such as the single-rail logics, seem to be promising candidates, because they...
This paper demonstrates some fundamental logic gates employing two phase clocked adiabatic static CMOS logic (2PASCL) circuit techniques. We design and simulate NOT, NAND, NOR, and XOR logic gates on the basis of the 2PASCL topology using SPICE implemented using 0.18 ??m CTX CMOS technology. For NOT circuit, analytical and simulation values are compared. From the simulation results, we find that 2PASCL...

We evaluate NOT, NAND, XOR and NOR logic gates on the basis of the 2PASCL topology using SPICE implemented using 0.18 ??m CTX CMOS technology. For NOT circuit, analytical and simulation values are compared. By removing the diode from...
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) employing 2PASCL circuit technology. Energy dissipation in the 2PASCL RCA is 71.3% lesser than that in a static CMOS RCA at transition frequencies of 10-100 MHz.
This paper proposes a novel two-phase drive adiabatic dynamic CMOS logic circuit (2PADCL). The proposed 2PADCL uses two complementary sinusoidal power supply clocks and resembles behavior of static CMOS. As a result, the delay time of the 2PADCL is shorter than that of the conventional ADCL circuit in the second and subsequent stages. The structure of 2PADCL can be also directly derived from static...
