Abstract :
A high resolution RFID reader, collecting neural data from implanted electrodes is proposed. The system is powering the implant using a class E power amplifier (PA) and in between receives the data by an asynchronous demodulation. The technology used is a standard 65 nm CMOS TSMC. Simulations reveal an average power consumption of the overall system of 19 mW with a supply of 1.2 V at 300 MHz of carrier frequency and a BER of 0.3%.
