摘要

提出了世界上第一个集成模拟前端(AFE)和音频编解码器IC支持WCDMA标准。该芯片采用英特尔0.18 /spl mu/m闪存+逻辑+模拟(FLA)工艺技术，采用0.35 /spl mu/m特征尺寸模拟晶体管。AFE传输路径包含一个10位分段R2R D/ a，自校准有源RC滤波器和带自调谐偏移校正电路的可编程增益放大器(PGA)。接收路径包括一个可编程增益有源RC滤波器和一个内置偏移校正的8位a /D。该AFE工作电压为2.7 V，电流消耗为55ma，总有效面积为15mm /sup /。

Analog front end IC for 3G WCDMA

Presents the world's first integrated analog front-end (AFE) and audio codec IC supporting the WCDMA standard. This chip was fabricated on Intel's 0.18 /spl mu/m flash+logic+analog (FLA) process technology using a 0.35 /spl mu/m feature size analog transistor. The AFE transmit path contains a 10-bit segmented R2R D/A, self-calibrated active RC filter and programmable gain amplifier (PGA) with a self tuning offset correction circuit. The receive path includes a programmable gain active RC filter and an 8-bit A/D with built-in offset correction. The AFE operates at 2.7 V with a current consumption of 55 mA, and total active area of 15 mm/sup 2/.
