Abstract: A fully integrated high linearity differential power amplifier driver with an on-chip transformer in a standard 0.13-μ m CMOS process for W-CDMA application is presented. The transformer not only accomplishes output impedance matching, but also acts as a balun for converting differential signals to single-ended ones. Under a supply voltage of 3.3 V, the measured maximum power is larger than 17 dBm with a peak power efficiency of 21%. The output power at the 1-dB compression point and the power gain are 12.7 dBm and 13.2 dB, respectively. The die size is 0.91 × 1.12 mm2.
