This thesis has two parts including the design of outer transmitter for implantable system and the power and data recovery circuits. The transmitter includes two circuits: a PSK modulator and a Class-E amplifier.

The necessary power and data in the implantable system receiving from the RF coupling and transmitting to the inside circuit are AC signals. By way of the rectifier and the voltage regulator, the DC signal can be obtained to provide supply voltage to the internal circuit and to be pumped to the high voltage(5V) for stimulation requirement. In addition, the received signals including clock and data information can be extracted by PSK demodulator and clock recovery circuit. The overall circuits with core area of 0.07mm2 have been implemented in a TSMC 0.35μm 2P4M standard CMOS process technology. Measurement results show that the low power on-chip LDO regulator provides a stable 1-V DC supply voltage and the digital data as well as the 256kHz clock are obtained precisely.
