Neste estudo, a compensação AM-PM da técnica de neutralização de capacitância de acoplamento cruzado é discutida. Cgd a neutralização leva à compensação AM-PM de um amplificador de potência com alteração insignificante nas características AM-AM. A compensação AM-PM foi confirmada através de análises e medições do circuito. A análise da formulação mostrou que a compensação AM-PM pode ser derivada via gm variação em relação à potência de entrada com neutralização de capacitância. Um amplificador de potência diferencial com neutralização de capacitância foi fabricado com transistores GaN de alta mobilidade eletrônica. A característica AM-PM do amplificador de potência diferencial fabricado foi medida em 17.7 GHz. Ele apresentou redução AM-PM de 22° em comparação com um amplificador de potência monofásico sem neutralização de capacitância com potência de saída de 35 dBm.

Abstract: In this study, AM-PM compensation of the cross-coupled capacitance neutralization technique is discussed. Cgd neutralization leads to AM-PM compensation of a power amplifier with negligible change of AM-AM characteristics. AM-PM compensation was confirmed via circuit analysis and measurements. The formulation analysis showed that AM-PM compensation can be derived via gm variation against input power with capacitance neutralization. A differential power amplifier with capacitance neutralization was fabricated with GaN high-electron-mobility transistors. The AM-PM characteristic of the fabricated differential power amplifier was measured at 17.7 GHz. It showed AM-PM reduction of 22° at compared to a single-phase power amplifier without capacitance neutralization at output power of 35 dBm.
