| 摘 要： | 在ＪＦＥＴ作输入管的代噪声高精度运放中，为了进一步减小输入偏流，增大输入阻抗，可使顶、背栅分离，且仅以顶栅接输入信号，而背栅接片内控制电路。本文将分析一种用于对这种ＪＦＥＴ背栅电平进行动态稳定控制的电路。

| Abstract: | When JFET is used as a low-noise and high-operational amplifier in input tube, plate fond and back grid can be separated to decrease input bias and increase input impedance. Besides, plate fond can receive input signal alone, and back grid connects the control circuit in the plate. This paper is going to analyze a control circuit to stabilize dynamically the electrical level in JFET back grid. |
