  • Abstract
    This paper presents a ΣΔ DAC with channel filtering for multi-standard wireless transmitters. It can be digitally programmed to satisfy specifications of WCDMA, TD-SCDMA and GSM standards. The measured SFDR are 62.8/60.1/75.5 dB for WCDMA/ TD-SCDMA/ GSM mode, respectively. The ΣΔ DAC manufactured in SMIC 0.13-μm CMOS process occupies a 0.72 mm2 die area, while drawing 5.52/4.82/3.04 mW in WCDMA/TD-SCDMA/GSM mode from a single 1.2-V supply voltage.
