Bias adapted operation of CMOS PA for handset application

Abstract

Summary form only given. The CMOS PA becomes a reality due to the active research work in recent years. But the performance is not up to the expectation because of the inherent problems of CMOS such as low power density and poor linearity. To enhance the performance further, various adaptation techniques are applied to CMOS PA, i. e. at the gate and drain. In this talk, we will introduce the advanced CMOS PA with the adaptaions.
