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...
Simultaneous switching noise (SSN) causes signal degradation to the high-speed interfaces among CMOS VLSIs. To achieve SSN simulation with a high accuracy, accurate models for chips, packages and printed circuit boards (PCBs) are required. However, such accurate simulation models are not currently available, since chip vendors do not release the value of on-chip capacitance and the detailed package...
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...
This paper demonstrates the low energy operation of 4-bit ripple carry adder (RCA) employing two phase clocked adiabatic static CMOS logic (2PASCL) circuit techniques. 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...
In this paper, a modeling of frequency depended dielectric dispersive characteristics of transmission line and its step responses are described. A dielectric dispersive characteristic can be shown by complex relative permittivity of medium. The Debye type and the Lorenz type dispersive characteristics are investigated. The equivalent circuit representations of per unit length parameters of the transmission...
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.
The new SET characterization technique for 0.15 mum Fully Depleted CMOS/SOI digital circuitries was investigated using SPICE and TCAD simulations. The SPICE simulation with a switch can readily reproduce the corresponding SET voltage response for a certain LET. This technique is valid as an alternative in all load and complementary transistor conditions, irrespective of the presence of a plateau region...
