Wireless implantable telemetry systems are suitable choices for monitoring various physiological parameters such as blood pressure and volume. These systems typically compose of an internal device implanted into a living body captures the physiological data and sends them to an external base station located outside of the body for further processing. The internal device usually consists of a sensor interface to convert the collected data to electrical signals; a digital core to digitize the analog signals, process them and prepare them for transmission; an RF front-end to transmit the data outside the body and to receive the required commands from the end station; and a wireless power supply. The digital core plays an important role in these systems since the data must be digitized and processed before transmitting to the end station for further processing. In this thesis, we presented an FPGA-based prototype for controlling and processing core of a miniature implantable telemetry system that is used to monitoring physiological parameters of laboratory small animals. The presented module samples and digitizes the collected data using an analog to digital converter, stores the collected data, generates the controlling output commands, processing the received data, and controls the power consumption of the system. The circuit is prototyped and experimentally verified using an FPGA development platform, then synthesized and simulated in 130 nm CMOS IC technology using standard digital cells. The overall core design occupies 1.6 mm × 1.6 mm CMOS area, and consumes 14.5 mW (IC) or 208 mW (FPGA) total power.
