摘要：
An amplifier includes a gain transistor including a control terminal to receive an input signal. A degeneration inductor is coupled between the first terminal of the gain transistor and ground. A shunt inductor and a capacitor are coupled in series between the control terminal of the gain transistor and ground, and form a filter to attenuate frequencies of the input signal within a frequency range. The degeneration inductor and the shunt inductor form a transformer to provide impedance matching.
摘要（中）：
放大器包括增益晶体管，其包括用于接收输入信号的控制端子。 退化电感器耦合在增益晶体管的第一端和地之间。 并联电感器和电容器串联耦合在增益晶体管的控制端和接地之间，并形成滤波器以在频率范围内衰减输入信号的频率。 变性电感器和并联电感器形成变压器以提供阻抗匹配。
