Abstract

In this paper, we present a design approach for an ASIC PulCar able to measure in continuous and real time heartbeat rate, and to display it. PulCar gives an audible alarm when this heartbeat rate exceeds a specified threshold. This VLSI circuit processes a digitalized analog signal, provided by an optoelectronic sensor. It is synthesized by Syncirc, a new CAD software which involves the development of the principle layout of a numerical circuit. This ASIC includes about 22,000 transistors in a 2 mm² chip.
