Ultra-low power consumption three-valued counting unit and multi-bit counter based on Domino circuit

Abstract

The invention discloses an ultra-low power consumption three-valued counting unit and a multi-bit counter based on a Domino circuit. The three-valued counter is designed with a switch-signal theory as guidance and combining the heat insulation logic, the multi-value logic and a Domino circuit. A three-valued positive cycle gate circuit switch-level structure with an Enable Pin is deduced first, a three-valued heat insulation Domino text arithmetic circuit and a heat insulation Domino bumper are combined to obtain a three-valued counting unit (namely, a single-bit three-valued counter). Then, a three-valued counter Enable signal generating circuit structural formula is deduced, and the three-valued counting unit and the three-valued counter Enable signal generating circuit are in cascade connection to obtain the three-valued multi-bit counter. According to Spice software simulation, the ultra-low power consumption three-valued four-bit counter based on the Domino circuit has the advantages of being correct in logic function and capable of saving power consumption by approximately 63% compared with a traditional three-valued four-bit Domino counter.

Description

technical field [0001] The invention relates to a three-value counter, in particular to an ultra-low power consumption three-value counting unit and a three-value multi-bit counter based on a domino circuit. Background technique [0002] Counter is one of the basic modules in large-scale integrated circuits. It is widely used in frequency dividers, encoders, memories and arithmetic operation circuits. The design of ultra-low power consumption counters has attracted the attention of circuit designers. At present, there are many design schemes for low-power counters, such as the method of reducing the power supply voltage and double-edge triggering, etc., which reduce the power consumption of the counter to a certain extent. However, the energy in these traditional counter circuits is consumed from the power supply to the ground at one time, and the energy utilization rate is low. The adiabatic counter using the AC pulse power supply can break through the limitations of the t...

Problems solved by technology

However, most of the current multi-valued circuits are designed with binary components, and the circuit complexity is relatively high. Combining the domino circuit with the advantages of fast speed and small area with multi-valued logic can simplify the circuit structure and improve the circuit to a greater extent. information density
