    • A self-biased cascode amplifier circuit includes first and second transistors connected in series and coupled between a dc voltage source terminal and a common terminal. An input signal terminal is coupled to a control electrode of the first transistor, and an output signal terminal is coupled to an output terminal of the second transistor. An integrated bias circuit is coupled between the dc voltage source terminal and the common terminal for internally biasing both the first and the second transistors without the use of an external bias supply or a direct bias connection to the dc voltage source. This arrangement provides a fully self-biased cascode amplifier circuit having improved performance and a simple and compact configuration.
    • 自偏置级联放大器电路包括串联连接在直流电压源端子和公共端子之间的第一和第二晶体管。 输入信号端子耦合到第一晶体管的控制电极,输出信号端耦合到第二晶体管的输出端。 集成偏置电路耦合在直流电压源端子和公共端子之间,用于内部偏置第一和第二晶体管,而不需要使用外部偏置电源或与直流电压源的直接偏置连接。 这种布置提供了具有改进的性能和简单且紧凑的配置的完全自偏置共源共栅放大器电路。
