In this paper, a three-stage rail-to-rail class-AB amplifier for GaAs/GaN PA driver in radar transmitter components is achieved using a proposed frequency compensation scheme in 0.35 μm CMOS technology. Meanwhile, a negative voltage reference is proposed with low un-trimmed spread by employing level shift technique. The PA driver capable of handling load capacitance ranging from no load to 1uF only consumes 2 mA of quiescent current while delivering a peak current of 100 mA to the load with −90 dB THD. The core area occupies 2.4mm².

一个2 mA PA驱动器，具有三级AB类轨至轨放大器，能够处理1μF负载电容

本文采用0.35μmCMOS技术中提出的频率补偿方案，实现了用于雷达发射机组件中GaAs / GaN PA驱动器的三级轨到轨AB类放大器。同时，通过采用电平移位技术，提出了一种具有低未修整扩展的负电压基准。能够处理从空载到1uF的负载电容的PA驱动器仅消耗2 mA的静态电流，同时以−90 dB THD向负载提供100 mA的峰值电流。核心区域占2.4mm ²。
