A 2.4 GHz transmitter front‐end with a wideband active balun is proposed.The wideband active balun is able to work ideally by adopting a resistive compensation technique, which balances the gain of the differential input. In addition, a variable‐gain preamplifier driver with a dynamic range of 18 dB is utilized for the autogain loop control feature. The proposed wideband active balun only occupies 15 × 27 μm 2 , which is profoundly small compared with conventional baluns and is promising in the differential to single signal conversion in wideband applications. © 2012 Wiley Periodicals, Inc.
