资料介绍

提出了一种拓展带宽的新型电路拓扑结构,该结构由四级射极跟随器级联而成,通过自适应有源偏置电路调节各级晶体管跨导,以及改变级间电感与后一级射极跟随器的结电容cbe谐振峰的频率位置来拓展带宽。对其工作原理和稳定性进行了分析,并基于2μmInGaP/GaAsHBT工艺,设计了应用此结构的宽带放大器。仿真结果表明:新型电路拓扑结构能有效地扩展带宽,提高增益。在2GHz~8.5GHz的频率范围内,增益达到20dB,增益平坦度小于±0.5dB,P1dB点输出功率大于17dBm。

A novel circuit structure of amplifier with the performance of wide bandwidth was designed, which consists of four cascaded emitter-followers. The bandwidth is expanded by adjusting each stage of transistor transcon- ductance by adaptively active bias circuit, and controling the resonant frequency, which is realized by adjusting inter-stage inductors and the junction capacitance Cbe of the next emitter-followers. The principle and stability of this structure were analyzed in detail. A broadband amplifier of this novel structure was designed based on 2 p,m InGaP/ GaAs HBT technology. Simulation results show that the new circuit structure can effectively improve gain-bandwidth product. In 2 GHz ~8.5 GHz fre...
