A 0.82 V Supply and 23.4 ppm/°C Current Mirror Assisted Bandgap Reference
2021 32nd Irish Signals and Systems Conference (ISSC)(2021)
Abstract
Traditional BGR circuits require a 1.05V supply due to the VBE of the BJT. Deep submicron CMOS technologies are limiting the supply voltage to less than 940mV. Hence there is a strong motivation to design them at lower supply voltages. The supply voltage limitation in conventional BGR is described qualitatively in this paper. Further, a current mirror-assisted technique has been proposed to enable...
