Abstract

We report a super low power MICS band receiver for a high resolution epi-retinal prosthesis (BionicEye). The FSK receiver consumes less than 1.5 mW power with 1 V supply. It can achieve a maximum data rate of 400 kb/s. In this paper, we present the research work carried out on designing a fully-integrated sub-threshold receiver fabricated on a 65 nm CMOS chip. In order to achieve super low power consumption, more than 90% of the transistors in all analog building blocks are operated in sub-threshold region. System level issues, such as required receiver architecture and specifications are also addressed.
