基于片上变压器耦合的CMOS功率放大器设计
Design of on-chip transformer-based CMOS power amplifier
摘要
Abstract
A fully integrated CMOS power amplifier (PA) operating at 2 GHz was designed, with on-chip transformers-based match networks used to realize the conversion of single-end between differential signals and the impedance match of input and output port. On-chip transformer was simulated using electromagnetic simulator ADS Momentum, and the efficiencies of input match, inter-stage and output match networks were 74.2%, 75.5% and 78.4%, respectively. The PA was designed and simulated in Agilent’s ADS using TSMC 65 nm CMOS spice model. According to the simulation results of PA operating at 2 GHz and supplied 2.5 V, input and output impedances are fully matched to 50Ω(S11 = –22.4 dB,S22= –13.5 dB), power gain is 33.2 dB, the saturated output power is 23.4 dBm, the maximum PAE is 35.3%, and the chip’s area is only 1.01 mm2.关键词
