Comparative Analysis of CMOS Adders Circuits Based on 10 Transistors

摘要

Development of digital signal processing devices has led to appearance of a series of CMOS circuit designs of arithmetic and logic blocks with a small number of transistors. In this paper we suggest a classification of full single-bit CMOS adders, circuits of which consist of 10 transistors. The comparison of main characteristics of adders has been carried out based on the results of circuit simulation for 0.18-micron MOS technology and the most promising implementations have been marked out.
