A 3b ΔΣ-modulated mismatch-shaped DAC is presented. The mismatch shaper uses 7 tunable 1.5b switched-capacitor bandpass ΔΣ modulators to dynamically route the digital signals to the DACs. The DAC can generate narrowband signals from 250 to 750MHz with ≥68dB SNR, ≥74dB SFDR, and -80dBc intermodulation distortion.
