Abstract―This paper describes a reconfigurable analog front-end (AFE) and audio Codec IC supporting the wideband code division multiple access (WCDMA) standard. The chip is fabricated on Intel’s 0.18- m (SOC) flash logic analog (FLA) process technology using a 0.35- m feature size analog transistor. The transmit path contains a 10-bit segmented rail-to-rail digital-to-analog converter, automatically tunable active RC filter, and programmable gain amplifier (PGA) with self-tuning gain and offset correction circuit. The receive path incorporates a PGA, active RC filter, and an 8-bit analog-
