Preceding in-vivo tests are being performed with a dedicated system based on the impedance converter AD5933, and a two-electrode configuration bioimplantable capsule. Acquired results will allow the optimal design of an implantable and autonomous low-power system. The implantable microsystem is being designed and simulated employing low-power techniques in a 0.35μm CMOS standard process.engBioimpedance measurementlow-powerartificial inseminationconference paper10.1016/j.proche.2009.07.126
