Video streams, Real-time Video Phone and all the other video concerned services should be achievable for the next generation cellular system. Moreover, the accessibility to the WLAN (Wireless Local Area Network) is a must for advanced personal information services. All the demands lead to a clear system requirement: Multi-mode ability and Wide transceiving bandwidth.
In the thesis, a multi-mode of GSM/WCDMA/WIFI IF digitizer is proposed and analyzed. An alternative low-distortion cascaded bandpass delta-sigma modulator is proposed and used to construct the multi-mode IF digitizer. The prototype chip is designed and implemented in TSMC 0.35 CMOS process with 3.3V power supply.
