Abstract :
This paper presents a mixed signal biomedical system implanted in human body to deliver appropriate therapies for atrial tachycardia and fibrillation. The diagnosis of the heart conditions is made with atrial electrograms (EGMs) sensed from within the heart. The system consists of three main parts: 4th order band-pass filter, ADC, and bio-signal processor. All parts are incorporated into a single chip. The chip is fabricated in a 0.35 μm CMOS technology. The chip area is 3.8 x 2.7 mm2.
