Abstract :
This paper describes two CMOS bandgap reference circuits featuring dynamic-threshold MOS transistors. The first bandgap reference circuit aims at application in low-voltage, low-power ICs that tolerate medium accuracy. The circuit runs at supply voltages down to 0.85 V while consuming only 1 μW; the die area is 0.063 mm2 in a standard digital 0.35-μm CMOS process. The second bandgap reference circuit aims at high accuracy operation (σ=0.3%) without trimming. It consumes approximately 5 μW from a 1.8-V supply voltage and occupies 0.06 mm2 in a standard 0.35-μm CMOS process
