Abstract

To accommodate drastically different symbol rates, signal bandwidth and SNR requirements between WCDMA and GSM, the IF frequency, sample-rate and converter architecture are optimized for a dual-standard /spl Sigma//spl Delta/ modulator. In the system and circuit design, attention is given to low power consumption to achieve 13.5 mW at 18 MSample/s. Measured dynamic range is 53 dB for WCDMA and 84 dB for GSM.
