Problems solved by technology

The dual-rail structure of the input signal makes circuit layout and wiring difficult, and the signal transmission structure of dual-rail input and dual-rail output requires symmetrical logic input signals, so the number of transistors is relatively large, which makes the layout and wiring in the design more complicated; some traditional The output node of the adiabatic logic circuit is suspended, so that the output level is easily affected by the noise in the circuit due to the coupling effect of the parasitic capacitance, causing the circuit to fail to work normally; (Efficient Charge Recovery Logic, referred to as ECRL) circuit, causing more energy loss in the circuit

Abstract

The invention discloses an adiabatic logic circuit, which is characterized by comprising a logic assignment circuit, an energy recovery circuit and a first N-channel metal oxide semiconductor (NMOS) transistor, wherein the energy recovery circuit consists of a first P-channel metal oxide semiconductor (PMOS) transistor and a second PMOS transistor. The adiabatic logic circuit has the advantages that a logic signal is only input into single module of the logic assignment circuit, a normal phase output signal is output from the grid of the first PMOS transistor, and an inverse output signal is output from an energy transmission end of the logic assignment circuit; the circuit structure adopts signal transmission manners of one-way input and two-way output, so that circuit design is simplified, the quantity of transistors is reduced, and cascade connection between the circuit and other unit circuits is easier; furthermore, as the energy transmission end of the logic assignment circuit is connected with the grid of the first NMOS transistor and the first NMOS transistor has the function of clamping, an output node is prevented from floating to some extent, the output performance of the circuit is improved, and the power consumption of the whole circuit is effectively reduced finally.

Description

Technical field [0001] The invention relates to an adiabatic circuit structure, in particular to an adiabatic logic circuit and a one-bit full adder. Background technique [0002] Nowadays, the design process of integrated circuit technology has entered the nano stage. In the process of chip design, no matter from the cost and performance of the chip itself, or from the perspective of the market of electronic information products, power consumption has become an important indicator to measure chip performance. Low-power design has become a hot and difficult point in current chip design. [0003] The adiabatic circuit is also called the energy recovery circuit. It has been widely used in the design of large-scale integrated circuits in the recent period and is a new type of low-power circuit design technology. Its basic principle is to use an AC power supply to supply power to it. By recovering the charge of the node capacitance, the energy in the circuit is reused many times to ac...
