摘要：This paper describes the development of a low-power instrumentation amplifier (IA) intended for use in recording of the human electrocardiogram (ECG). With the wide-swing cascade bias circuit design, the IA realizes a very high power-supply rejection ratio (PSRR), and can be operated at signal supply voltage in the rage between 2.5 and 5.5V. It was fabricated using 0.5um double-poly triple-metal CMOS technology, and occupies a die area of 0.2mm(2). The amplifier provides a gain of 40dB and has high common-mode rejection ration (CMRR) better than 100dB. The IA has a power consumption of 160uW operating from a 3.3V power supply.
