A Volterra-Series-Based Design Technique for the Bias Circuit of Class-AB RF Power Amplifier
2018
T31 paper presents a novel radio frequency (RF) power amplifier (PA) design technique based on Volterra Series analysis. This design technique is able to calculate the nonlinearity of the PA circuit. In Class-AB RF PA design, the best bias circuit for the balance between efficiency and linearity can be calculated by using this design technique. Consequently the period of PA's design and experiment can be shortened. A test die is fabricated and the measurement result verifies the effectiveness of this design technique.
