Digitization from IF or RF using an LC bandpass ΔΣ modulator avoids the traditional problems of direct-conversion receivers, such as EVM degradation due to IQ imbalance, 2nd-order intermodulation, and AGC interaction with DC offset correction settling. Our target application is a low-power IEEE 802.11n receiver for 2.4 to 2.5GHz using a fixed 3.2GHz clock and IF tuned from 700 to 800MHz (see Fig....
