Design of a multifunctional small digital integrated circuit (IC) using 180nm CMOS Technology

Abstract

This article presents a multifunctional digital integrated circuit(IC)and the integrated circuit performs four tasks separately namely, 555 Timer, Multiplexer, Counter, and Flip-Flop. The certain task is chosen by selecting two-line input four output demultiplexers. The 555 timer IC performs three different modes such as monostable, astable, and bistable mode. These modes are chosen by a given input pattern. The design is delivered by a 1. 8V direct current supply with a difference ofO.lv. The proposed design consumes 11.41mW power which is reliable. These circuits are depicted by Semi-conductor Laboratory (SCL) 180nm Technology in Cadence Virtuoso Analog Design Environment.
