Radio frequency bandpass delta-sigma analog-to-digital converters and related methods
Radio-frequency (RF) receivers having bandpass sigma-delta analog sigma analog-to-digital converters (ADC) designed to digitize signals in the RF domain are described. Such bandpass ADCs utilize one or more of the following techniques to enhance noise immunity and reduce power consumption: generation of in-phase (I) and quadrature (Q) paths in the digital domain, nth order resonant bandpass filtering with n>1, and signal sub-sampling in an ith Nyquist zone with i>1.
