Abstract

An ultra wide dynamic range voltage reference operating with power consumption of pico-watt has been designed for a retinal prosthesis device using IBM 65nm CMOS process. The temperature coefficient is zeroed at 37°C while achieving 2.5 ppm/°C over the range from 25°C to 75°C. A perfect suppression of the supply voltage dependence is realised to provide line sensitivity of 0.04%/V with ultra low input voltage of 0.5 V up to 3.5 V. The power supply noise attenuation is simulated to maintain at 100 dB across whole frequency band up to 100GHz. The occupied chip area is maintained as low as 0.003 mm ² with size of 35μm by 75μm.
