  • Abstract
    This paper describes a bandgap reference fabricated in a 0.5-μm digital CMOS technology without resistors. The circuit uses ratioed transistors biased in strong inversion together with the inverse-function technique to produce a temperature-insensitive gain applied to the proportional to absolute temperature (PTAT) term in the reference. After trimming, the peak-to-peak output voltage change is 9.4 mV from 0°C to 70°C. It occupies 0.4 mm2 and dissipates 1.4 mW from a 3.7-V supply
