ASIC for wireless ambulatory blood pressure monitoring based on applanation tonometry

This paper describes a 0.18-μm CMOS ASIC, featuring a low power and highly integrated 802.15.4 transceiver with MAC support, a 100-μA programmable signal conditioning, and an inductor-less power management circuit. A compact sensor node for wireless ambulatory blood pressure monitoring (ABPM) using this ASIC is demonstrated. The whole ASIC including the Zigbee transceiver shows state of the art performance in terms of high level of integration and low power consumption.
