Abstract :
A novel linearization method for CMOS drive amplifier using intermodulation distortion (IMD) canceller is presented. The IMD cancellation method is composed of a cascode main amplifier and a common-source IMD canceller. The additional common-source amplifier generates IMD3 signals with 180deg phase difference against the IMD3 of the cascode main amplifier. The linear drive amplifier is designed and fabricated by CMOS 0.18 mum process. The output IP3 of +13 dBm is achieved with the power gain of +11.6 dB, the output P1 dB of + 5.5 dBm, and the power-added efficiency of 21%.
