Abstract

The current paper presents a fully integrated CMOS RF front-end circuit with low-power consumption for passive 13.56 MHz biomedical implants. The 13.56 MHz carrier frequency of the binary phase shift keying (BPSK) signal is transmitted to the body through the external and internal coils. The full-wave bridge rectifier of biomedical implants rectifies the BPSK signal received from the internal coil, and it is converted into DC power supply by the linear regulator to generate a stable DC output of 1.8 V. The fully digital BPSK demodulator demodulates the received BPSK signal for the clock/data separator to recover clock and data, which are required by the back-end circuit. This chip is designed and fabricated in TSMC 0.18 μm 1P6M CMOS technology, with an area of 1.35 mm 2 and power consumption of 632 μW.
