Abstract
A novel current-mode bandgap reference (BGR) with second-order temperature compensation is presented. The proposed bandgap reference adopts a novel structure, which takes advantage of the complementarity of second-order temperature coefficients of triodes and subthreshold MOSFETs to provide an output with second-order temperature compensation. The bandgap reference is implemented in SMIC 0.18μm RF technology, and simulation results show that it can provide the output voltage of 510 mV with temperature coefficient of 0.6 ppm/°C over the temperature range of -20°C ~ 80°C.
