Abstract

An auto-zero (AZ) technique to cancel offset and drift in a bio-implantable integrated circuit is discussed in this paper. The implemented circuit is designed for monitoring blood pressure of transgenic mice. Due to small available volume, the power consumption is the primary design issue. In order to reduce the power consumption, techniques at the system level as well as circuit level are used. The auto-zero technique used in this IC helps reduce the complexity of the circuit blocks; which consequently results to lower power consumption. The chip is fabricated in 0.18 mum standard CMOS technology. The simulation and measurement results of the implemented chip will be presented.
