Abstract :
This paper addresses the realization of digital arithmetic circuits in CMOS, the currently most important technology for integrated circuit implementations. Concrete designs of the basic arithmetic circuits like those of half adders, full adders, ripple carry, carry lookahead and conditional sum adders are investigated. Simple mappings from gate-level designs to CMOS realizations and optimized CMOS implementations are examined and compared in terms of their circuit complexities and latencies.
