Tri-valued, thermal-insulating and low-power adder unit and adder

Abstract

The invention discloses a tri-valued, thermal-insulating and low-power adder unit and an adder. The adder unit controls each NMOS tube in an input signal sampling circuit to sample input signals by using a clock-controlled clock signal; four corresponding summing circuit modules and carry output circuits with cross storage-type structures are constructed by sampled values according to required realized addition logic relationship through the bootstrap operation of the NMOS tube; power clocks phi1 and phi complete the evaluation and energy recovery of the output load to realize correct logic function; and compared with a DPL tri-valued adder, the four-digit tri-valued thermal-insulating and low-power adder can save energy consumption by about 90 percent in 0.9 microsecond, and has distinct low-power characteristics.

Description

technical field [0001] The invention relates to an adder, in particular to a ternary adiabatic low power consumption adder unit and the adder. Background technique [0002] The adder unit (that is, the full adder) is the basic unit of the arithmetic circuit and one of the key components of the digital circuit system. Optimizing its design is the key to obtain a high-performance arithmetic circuit. So far, there have been various full adder design schemes, such as "45nm Low Power Consumption, High Performance Zipper CMOS Domino Full Adder Design" disclosed in the Journal of Electronics (Authors: Wang Jinhui, Gong Na, Geng Shuqin, etc.), which utilizes Charge self-compensation technology designs Zipper CMOS domino full adder to reduce power consumption by discharging dynamic nodes of P-type domino circuits to charge dynamic nodes of N-type domino circuits; Swing Complementary Pass-transistor Logic Adder" (Author: Wang Zongjing, Qi Jiayue), which uses a double differential str...
