A super low power and high data rate MICS band (402MHz-405MHz) wireless transceiver has been proposed and is being simulated. This transceiver would be implanted as a part of the high resolution epi-retinal prosthesis for data transmission, communicating with the external device, which also works at MICS band. In order to achieve super low power consumption and high data rate, a bunch of advanced techniques and skills are and will be adopted:

Current Results:

• The main circuit of the transceiver has been built in schematic and has been simulated. Current results show that the average estimated power dissipation is less than 1mW (RX<1mW, TX<1mW). The data rate could be higher than 700kbps.
• Both contour-radial-mode and wine-glass mode nickel disk resonators (MEMS resonators) have been simulated. Simulations show that their Q factor are larger than 9000 (when working at 300MHz)

This transceiver uses various techniques and skills to achieve super low power and high data rate. Thus it is very suitable for all implantable medical devices. It will be fabricated on one single chip and implanted as a part of the epi-retinal prosthesis to fulfill the data transmission function.
