Abstract
An architecture for oversampled delta-sigma (.DELTA.-.SIGMA.) analog-to-digital (A/D) conversion of high-frequency, narrow-band signals includes multistage .DELTA.-.SIGMA. modulators that incorporate band-reject noise shaping centered at one fourth the clock frequency Fs. These modulators cascaded with a bandpass digital filter also centered at a frequency of Fs/4 perform A/D conversion for high-frequency, narrow-band signals centered at the same frequency. The bandpass modulators are implemented by use of resonators in existing low-pass multistage modulators.
