Abstract

Full adders are one of the most important building blocks in VLSI digital arithmetic. The area, electrical, timing, power consumed and noise generated characteristics of this cell are strongly dependent on the design technique. An exhaustive work taking into account the above parameters is done, and that complete analysis will be of utility for the community of digital designers. Emphasis will be done in power/noise figures, of most important concern in current CMOS mixed-signal design. The full adders considered are those using complementary CMOS, pass-transistor logic, double pass-transistor logic, and two versions based on CMOS transmission gate. Main parameters as area, delay, power consumption and noise generation have been measured by electrical simulation in a 0.35 μm CMOS technology. The main results obtained are, on one hand, the selection of a logic family for a specific application and, on the other hand, the selection of a specific full adder structure for an optimized parameter option -power, noise or speed.
