提出了一种采用SiGe或GaAsIC工艺实现的双环阻性反馈功率/电流放大电路。仿真结果表明，在0.6 GHz到1.6 GHz的频率范围内，任何NFmin&lt；0.3db和FT&gt；20 GHz的工艺流程都能获得小于0.5db的总体噪声系数，小于-15db的输入回波损耗和平坦的增益
A dual-loop resistive-feedback power-to-current amplifier circuit to be implemented in SiGe or GaAs IC technology is presented. Simulation results indicate that any technology process with NFmin < 0.3 dB and fT > 20 GHz is able to achieve an overall noise figure less than 0.5 dB, an input return loss less than -15 dB and flat gain over a frequency range from 0.6 GHz to 1.6 GHz
