Abstract

A CMOS driver amplifier employs two design techniques to improve its linearity in wide output power level. First, multiple-gated transistor (MGTR) technique with two auxiliary transistors extends the linear region further compared with MGTR with single auxiliary transistor. Second, resistive source degeneration significantly suppresses the unwanted 2nd-harmonic feedback effect caused by an inductive source degeneration. A 2.4-GHz differential driver amplifier has been implemented in 0.18μm CMOS for Mobile WiMAX and Korean WiBro applications. It shows that the linear region with OIP3 of ≥+20dBm is extended up to an output power of - 5dBm, while achieving a maximum OIP3 of +28dBm, OP1dB of +7.8dBm, and a power gain of 9.2dB with dc power consumption of 1.8V and 18.7mA.
