摘要：

We present the worlds first integrated analog front-end (AFE) and audio codec IC Supporting the WCDMA standard. This chip was fabricated on Intel's 0.18mum flash +logic +analog (FLA) process technology using a 0.35mum 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(2).
