A bioimplantable telemetered blood pressure measurement system for transgenic mice

A system including an implantable integrated circuit (IC) for measuring the blood pressure of transgenic mice is implemented in 0.18 /spl mu/m CMOS technology. The system specifications and circuit design challenges are summarized and discussed in this paper. The implant part of the system is to operate with a single miniature battery for more than two month. The measured data is transmitted wirelessly to a base station. The power consumption of the implantable system is 38 /spl mu/W.
