"WebThe impedance of this circuit does not come from any change in voltage, but from the input and output impedances of the op-amp. The input impedance of the op-amp is very high (1 MΩ to 10 TΩ), meaning that the input of the op-amp does not load down the source and draws only minimal current from it. Because the output impedance of the op-amp is ... " - Input vs output impedance

WebAug 26, 2016 · The output impedance refers to the impedance, or opposition to current flow, of the component that often bears an electrical source to "drive" a load component. Meanwhile, the input impedance refers to the load component's opposition to current flowing in from the electrical source. WebA Perfect Match. Strictly speaking, a properly matched circuit is one where a circuit with a given output impedance feeds an input which has the same value input impedance. In other words, a 600Ω output feeding a 600Ω input is perfectly matched. This is important in any circuit where we're concerned with transferring the maximum amount of ...
