Abstract :
An on-chip implantable lock-in analyzer of variations of the electrical bio-impedance has been designed and pilot versions of the ASIC based analyzer have been fabricated and tested. A mixed signal approach, as the most suitable way for accomplishing a low voltage and low power ASIC for applications in portable and implantable devices for various biomedical applications, is discussed
