摘要

A high input impedance, high common mode rejection ratio, fixed gain (X100) amplifier is proposed for recording biopotential signals. This miniature amplifier affords the feature of power saving. It can continuously junction for as long as 3 months with a small battery (3.3 V, 2.2 g). A practical application of this amplifier for ECG recording has shown that it has great potential for recording other biomedical signals. Hence, this amplifier can be used as a building block at the front end of most biomedical systems. Detailed design considerations and circuit implementation of this amplifier are described to facilitate its acceptance as a common module for this purpose.
