  • Abstract
    Capacitor mismatch in a 1.5 b/stage pipelined ADC is self-trimmed with a zero-forcing calibration loop based on ΔΣ polarity detection. Signal-subtracted analog PN error correlation shortens background calibration time by a factor of 10. The 4.2×3.8 mm2 chip in 0.18 μm CMOS exhibits 1 LSB INL at 14 b, 84 dB SFDR at 30 MS/s, and consumes 350 mW at 3 V.
