摘要：
A curvature corrected bandgap reference (BGR) with 1ppm/degrees C temperature coefficient from -40 degrees C to 150 degrees C is presented. Random mismatch and 1/f noise are moved to high frequency by opamp chopping. Chopping ripple is removed by a switched capacitor notch filter which has a small area. It is designed in TSMC180 BCD process with 42uA current consumption and 0.06 mm(2) chip area.
