Abstract :
An integrated circuit for ECG measurements and preprocessing is presented. The circuit consists of four independent macro modules: (1) an analog instrumentation amplifier for ECG tracking, (2) a high-performance sigma-delta A/D converter, (3) a computationally efficient linear-phase digital filter for ECG preprocessing, and (4) an interface for digital and analog ECG output. A bit-serial approach has been chosen for digital modules to keep the circuit area and power consumption sufficiently small. The high-quality modules and versatile output facilities make the circuit very useful in all kinds of ECG monitoring
