This paper proposes a CMOS bandgap reference (BGR) circuit, which can successfully operate with sub-1-V supply. In the conventional BGR circuit, the output voltage V ref V ref V ref is the sum of the built-in voltage of the diode V f V f V f and the thermal voltage V T V T V T of kT=q kT=q kT=q multiplied by a constant. Therefore, V ref V ref V ref is about 1.25 V, which limits a low supply-voltage operation below 1 V. Conversely, in the proposed BGR circuit, V ref V ref V ref has beendoi:10.1109/vlsic.1998.688094 fatcat:2fpeoxoncbenzg3clzg6g2fek4
