| 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. |

| Abstract: |
| It is shown that by connceting an ideal vlltage-comtrolled currcnt source(VCCS)across the input teminals of a practical operational amplifier cmbedded in an inverting amplifier configuration the virtual ground Property can be extended to a frequency as high as unity-gain bandwidth of the operational amplifier used.practical realization of this VCCS using a real operational amplifier is given.By complementary transformation a noninverting amplifier configuration is obtained. |
