This paper presents a reconfigurable analog baseband channel for multistandard receivers. The circuit, consisting of two variable gain amplifiers and a low-pass filter, fulfills the requirements of GSM, WCDMA (UMTS), WLAN (IEEE 802.11a/b/g), and Bluetooth. The gain, bandwidth and power consumption of the circuit are changed through a digital control word depending on the selected standard. Simulation results, including all of the tests prescribed by the different standards, confirm the validity of the proposed solution. The in-band IIP3 evaluated with maximum gain (68dB/39dB) is 5dBm/1dBm for UMTS/WLAN respectively, while the power consumption is 51.7mW/55mW in the two cases
