Abstract :
The V0 of a voltage regulator changes with temperature and process variations to make the performance of subthreshold MOS logic almost insensitive to them. The propagation delay of a subthreshold CMOS inverter supplied by this regulator has a temperature sensitivity of 114ppm/degC and a relative standard deviation due to process variations of 4.9%. The regulator is fabricated in a 0.35mum process and draws 2.9 to 3.4muA from 1.8 to 4.3V over the 0 to 80degC range.
