Abstract
A 1V CMOS differential/floating bandgap reference circuit was implemented in a 0.18μm CMOS process. The bipolar bandgap core was biased by a differential input multiple-output transconductor driven by a fully differential opamp. The common-mode output voltage, Vcm, and the differential output voltage, Vdr, are both temperature compensated. The current consumption at 1V was 36μA. The untrimmed temperature coefficients for Vdr and Vcm were 89.3ppm/°C and 102.9ppm/°C, respectively. The line regulation was 2.9mV/V and the load regulation was 0.52mV/mA.
