Multisim-Based Digital Comparator Design and Performance Optimization

Nowadays, as many electronic products are moving towards increased portability and high reliability, higher demands are being placed on the various performance parameters of digital integrated circuits. Currently, digital integrated circuits are developing in the direction of low power consumption. Digital comparators are widely used in many areas of digital integrated circuits. Power consumption has an impact on many performance parameters of digital integrated circuits, so it is important to optimize power consumption during the design of digital integrated circuits. Therefore, a digital comparator consisting of CMOS logic gate circuits is designed and further, the comparator energy consumption is optimized and functional simulation is carried out using Multisim software in this paper. This paper describes the principles of the logic gates that make up the designed comparator, the design of the circuit according to the function of the comparator, and the calculation and optimization of the energy consumption of the digital comparator. Through analysis and calculation, the comparator is able to realize the numerical comparison function, and different numerical comparison results correspond to different output signals. After optimization, the comparator is able to achieve a reduction in power consumption.
