Full TextAbstract
A low-voltage low-power pacemaker Front-End for detecting QRS complex is presented in this paper. The circuit includes a switched-opamp switched-capacitor (SO-SC) preamplifier with a gain of 40db, a fourth-order Butterworth SO-SC filter with a sampling frequency of 1kHz, and an opamp with a new continuous time common mode feedback (CMFB) circuit which is able to operate with a very low supply voltage. The whole circuit operates with a supply voltage of 0.8V and consumes a power of 420nW.
