Abstract :
The exclusive biotelemetry system for implantable measurement utilizing a low-power BPSK transmitter, RF terminal chip for signal up-conversion and receiver is presented. The frequency band used in the human body is the un-licensed band at 402-405 MHz allocated to medical implant communication systems (MICS) by FCC and the ISM band at 2.4GHz is used for transmission in the air. This system has following characteristics: 40 channels with 75k bandwidth, low output power in transmitter and easily be full-integrated that are suitable for implantable applications. The low noise amplifier (LNA) with current reuse technique and cascode structure for high gain and low noise figure is implemented in this paper. The chip is designed and fabricated in TSMC 0.18 mum 1P6M CMOS technology.
