Abstract
This paper presents a high accuracy low-power bandgap voltage reference with trimming. A temperature coefficient of 12-22 ppm/°C from -40 to 125°C and a load regulation of 2 mV within 1.8-5.5v supply voltage are achieved under process variation and device mismatch. The proposed circuit has a PSRR of -60dB-72dB and consumes 11.6-15.2 μA, which is manufactured in GSMC 0.18 μm CMOS process.
