本文介绍了一种增益为54 dB、3 dB带宽为24 GHz的放大器。该放大器由三个差分级组成，采用两种不同的反馈技术，负责带宽扩展，没有任何明显的增益降低，以及相对平坦的增益响应，面积和功耗的增加可以忽略不计。该放大器采用3.3V电源供电，功耗为180mW，增益带宽积（GBP）为12 THz。
A 54 dB gain amplifier with a 3-dB bandwidth of 24 GHz is presented in this paper. The amplifier consists of three differential stages employing two different feedback techniques that are responsible for the bandwidth extension, without any noticeable reduction of gain, as well as a relatively flat gain response with negligible increase in area and power consumption. The amplifier consumes 180mW from a 3.3V supply and shows a gain-bandwidth product (GBP) of 12 THz.
