Abstract

This work uses the mutual temperature compensation of threshold voltage and carrier mobility to establish the optimum overdrive voltage for a MOS transistor. A fully differential SAR ADC is designed using 65 nm technology with improved temperature and process stability and can work under supply voltage of 300 mV. Simulation results show that under VDD of 300 mV the ADC is able to achieve a peak ENOB of 5.5 bits, with a variation of 0.7 bit over temperature range of-55 °C to 125 °C. Also the FOM of the ADC is 8.8 and 58 fJ/conversion-step at 27 °C and 125 °C, respectively.
