Abstract

A custom CMOS LSI for an implantable telemetry system hasbeen developed for acquisition of biomedical informations. This implantable system consists of four parts separated from each other, that is, command receiver, missing pulse decoder, functional memory and conditioner. They are all fabricated on one single silicon chip of 4×5mm2. The CMOS LSI's of this system are designed and implemented to get as small size and as low power consumption as possible. A specific implanted sensor is selected by a signal from the external circuit and its output signal is transmitted to the receiver by telemetry. Another function implemented in the system is baseline adjustment of the implanted sensors by external command signals. Using an internal pulse powered command receiver the system is capable of disconnecting itself from power source when it is not in use.
