  • Abstract
    The modulator of a bandpass analog/digital (A/D) converter, with 63 dB signal/noise for broadcast AM bandwidth signals centered at 455 kHz, has been implemented by modifying a commercial digital-audio sigma-delta (ΣΔ) converter. It is the first reported fully monolithic implementation of bandpass noise shaping and has applications to digital radio
