An ASIC Solution for Intelligent Electrodes and Active-cable Used in a Wearable ECG Monitoring System

• This paper describes a digital CMOS Application Specific Integrated Circuit (ASIC) solution with the complete data acquisition and transmission for the use in a wearable electrocardiography (ECG) monitoring system. The main particularity of this system is related to the proposed reconfigurable microchip architecture for an intelligent electrode. The chip area is 2.3 mm(2) in a standard 0.18 mu m CMOS technology. The chip is operating at 24 MHz system clock with 3.3 V power supply for I/O cells and 1.8 V for the core circuit respectively. The estimated dynamic power dissipation is only 857 mu W. The post-layout simulation results show that the microchip embedded inside an intelligent electrode features ultra low power consumption and is quite feasible for a hand-held Personal Health Assistant (PHA) which uses a battery as energy source.
