Abstract: A SINGLE CMOS CHIP, dual-chamber heart pacer, with a microprocessor architecture, and a variety of on-board analog signal processing, will be described. The micropower IC is fully mask and user programmable; Figure 1.Features of the microprocessor include: two on-board sense amplifiers capable of sensing 0.5mV haversine waves; two on-board output amplifiers capable of 1-12mA output current; eight different programmable pacer modes; user programmable rates, refractories and delays; telemetry output; chip fault…
