A 0.6V MOS-only voltage reference for bio-medical applications with 40ppm/0c temperature drift

Abstract

This paper exploits the CMOS beta multiplier circuit to synthesize a temperature independent voltage reference suitable for low voltage and ultra-low power bio-medical applications. The technique presented here uses only MOS transistors to generate PTAT and CTAT currents. A selfbiasing technique has been used to minimize the temperature and power supply dependency. A prototype in 65nm CMOS has been developed and occupies 0.0039mm, and at room temperature it generates a 204mV reference voltage with 1.3mV drift over a wide temperature range (from -40 to 1250C). This has been designed to operate with a power supply voltage down to 0.6V and consumes 1.8uA current from the supply. The simulated temperature coefficient is 40ppm/0C.
