双极型伴随运算放大器的特性及应用研究

Study on the characteristics and applications of BJT adjoint operational amplifier

应用伴随运算放大器将通用电压模式的电压运放电路转换为电流模式电路,提出一种双极型晶体管伴随运放电路,分析其开环特性,并利用其组成闭环电流放大器和五阶低通滤波器。

The concept of adjoint operational amplifier is introduced, which can transfer voltage-mode circuits into current-mode circuits. A BJT adjoint operational amplifier is designed, the open-loop characteristic of which is analyzed. A closed-loop current amplifier and a 5-order low-pass filter are formed based on the BJT adjoint operational amplifier.
