The implemented electronic system owns high CMRR characteristics to meet the requirement of bio-signal. The system is tested by a simulated cardiac signal generated from a patient simulator (Metron PS-420), and ECG signal from a healthy male subject (aged 23). . Keyword: FPAA, CMRR, ECG, Bioelectric Signal 1. INTRODUCTION The ease of weak bioelectric signal acquisition is an indispensable to all reliable medical diagnostic system. Traditionally, clinical professionals need different apparatus to obtain bio-signals for diagnosis. In this article, we have designed a front-end acquisition system using FPAA to measure different bio-signals without change of hardware circuitry. A Field-Programmable Analog
