of the capacitor) and is given the termimpedanceto make the distinction. It is thus more correct to speak of an amplifier having an input impedance rather than simply resistance, arising from the parallel combination of its input resistance and the impedance of the input capacitor. For DC and...

Looking at the input of the amplifier differentially and using the virtual-short concept (Figure 2) from an inverting-amplifier topology, we can express the input impedance as ZIN = RT || 2RG. For an example of how to select the value of RT, let's look at a differential source driving...
