Design of a Bi-Directional Wireless Data Transceiver for Implantable Biomedical Device

Abstract

In this paper, we have presented a high data rate transceiver with low power consumption. The major parts of our design are transmitter and receiver. We have used 180-nm CMOS process has been used for this purpose. Here, we have emphasized on the data rate, DC power consumption and frequency band of the transceiver. We have also compared how data rate and power consumption change according to the changes of frequency band. For 180 nm process both data rate and power consumption are 500 Mbps (simulation), and 3.65 mw respectively. The receiver part consists of a low noise amplifier (LNA), a mixer and a buffer. By simulating the LNA, we obtained the simulated gain of 16.94 dB, input matching (S11) of −20.84 dB, output matching (S22) of −20.81 dB, noise figure (NF) of 0.997 dB and power consumption of 3.491 mW when the frequency band of the LNA is 200 MHz – 10 GHz. The power consumption of the complete receiver is 4.18 mW. Simulation result shows that on the receiver side the digitized data rate is 100 Mbps.
