143N. Miller multiplication and effect, input impedance of common-source

[@joebobthe13th]

Thank you Professor, this explanation of Miller demystified the concept for me. Yet another wonderful lecture.

Do we have to consider the effect of R1 in order to calculate the resistor seen from Cmu?

[@ملكةزماني-ذ4ر]

Why we don't consider Miller effect in Common Gate configuration when we study high frequency response?

[@jorge-garcia-mateos]

The point between impedances Z1 and Z-Z1 with zero voltage, does also exist when the amplifier is not inverting? When it is not inverting there is not change of sign between input and output. Is there a formal demonstration of the existence of the zero volage point? Thanks in advance for your answers.

It would exist if you allow one of the impedances to be negative. Nonetheless, the point here is that since this point changes with frequency in general, one should use the time and transfer constant expression to get the most accurate result.
