  • Abstract Abstract:
      This thesis studies the memory effect due to bias perturbation on digital predistortion technique, and employs multi-tone continuous wave signal and digital modulation signals with different bandwidth to discuss the performance of digital predistortion technique. Memory effect makes a great impact on the digital predistortion technique, and bias perturbation is one of the major causes. Lowering the bias perturbation can improve the effectiveness of digital predistortion technique. Another focus of this thesis is to design a Class E power amplifier in 0.18 μm CMOS process. The power amplifier uses cascode structure to alleviate the breakdown voltage problem and employs power combining technique to achieve impedance transformation on chip for the purpose of increasing the output power and efficiency.
