Abstract
A single-chip, fully integrated GSM-EDGE/ CDMA2000/UMTS direct conversion receiver has been implemented. While the design comprises two frac-N PLLs, mixers, LNAs, fully integrated VCOs, analog anti-aliasing filters and a three-wire-bus configuration interface, the key topic is a fully configurable digital-front-end (DFE), ΔΣ ADCs and a high-speed digital serial baseband (BB) interface. The DFE's functionality includes sample-rate-conversion, channel filtering, dynamic range control, and signal conditioning for data transmission via a digital interface between RFIC and baseband IC. The described partitioning shifts some of the functionality, traditionally located in the analog-front-end (channel filtering, gain control, etc.) and baseband IC (matched filtering) to the digital-front-end. The receiver IC with a die size of 8 mm2 has been fabricated in 0.13-μm RF-CMOS. The power consumption for the DFE is 11 to 35-mW@1.5 V. The receiver shows a error-vector-magnitude (EVM) of 3.9 % in UMTS mode and 3.1 % in CDMA2000 configuration at the digital baseband interface
