  • Abstract
    A method for reducing the effects of random mismatches in CMOS bandgap references reduces effects of CMOS current-mirror offsets and input-referred offsets of CMOS opamps. The circuit is fabricated in a 0.18 /spl mu/m CMOS process. Measured 3 sigma output voltage distribution is /spl sim/1%.
