  • Abstract
    A 2nd-order 4b ΔΣ modulator in cascade with a 9b pipeline clocked at 80MHz achieves 75dB DR, 74dB peak SNR and more than 87dB SFDR in a 10MHz bandwidth by means of background digital linearization and noise-cancellation algorithms. The 0.18μm CMOS chip consumes 240mW including reference generator, digital decimator and correction logic.
