abstract   bibtex   
A reconfigurable analog-to-digital converter (ADC) based on a 2-2 modified cascaded sigma-delta (Σ-Δ) modulator designed for a GSM/WCDMA/WLAN/WiMax zero-IF receiver is now available. Employing the second-order feedforward Σ-Δ modulator in a 2-2 modified cascaded configuration, a high linearity over 100 kHz/2 MHz/10 MHz signal bandwidth can be achieved. Application of the P-DWA technique in the first feedback 4-b DAC eliminates the spurious tones associated with the multibit DAC nonlinearity in the WLAN/WiMAX modes.
