Abstract :
An analog baseband chain for a multistandard (Bluetooth, WCDMA/UMTS, and WLAN) reconfigurable receiver in a 0.13 mum CMOS occupying 1.65 mm2 is presented. The circuit consists of an open-loop programmable-gain amplifier (PGA1), an active-Gm-RC low-pass filter (LPF), and a closed-loop programmable-gain amplifier (PGA2). The chain gain can be programmed in the range -6 divide 68 dB, while the input-referred noise (IRN) is 5 nV/radicHz. A dynamic range (DR) larger than 82 dB is achieved for a 1% total harmonic distortion (THD). The current consumption is minimized and adjusted for the different operation conditions, down to 11 mA for the full chain.
