本文提出用一个理想电压控制电流源(VCCS)并接于嵌在一个倒相放大器电路中的实际运算放大器(OP.amp)输入端,虚地性质(VGP)可以扩展到使用的运算放大器单位增益带宽那样高的频率.文中给出用真正运算放大器的VCCS的实用电路.用互补变换法可得出非倒相放大电路图.
This paper proposes an ideal voltage controlled current source (VCCS) connected to the input of an actual operational amplifier (OP.amp) embedded in an inverting amplifier circuit. The virtual ground property (VGP) can be extended to the operational amplifier unity gain Bandwidth as high frequency.The article gives a practical circuit with a real operational amplifier VCCS.With the complementary transform method can be drawn non-inverting amplifier circuit.
