Although the term Miller effect normally refers to capacitance, any impedance connected between the input and another node exhibiting gain can modify the amplifier input impedance via this effect. These properties of the Miller effect are generalized in the Miller theorem. The Miller capacitance due to undesired parasitic capacitance between ...
The original Miller effect is implemented by capacitive impedance connected between the two nodes. Miller theorem generalizes Miller effect as it implies arbitrary impedance connected between the nodes. It is supposed also a constant coefficient ; then the expressions above are valid. But modifying properties of Miller theorem exist even when ...
The voltage gain of modern transistors can be 10–100 or even higher, and for op amps are orders of magnitudes higher, so Miller capacitance (first noted in vacuum tubes by John Milton Miller in 1920) is a significant limitation on the high frequency performance of amplifying devices.
John Milton Miller (June 22, 1882 – May 17, 1962) [1] was a noted American electrical engineer, best known for discovering the Miller effect and inventing fundamental circuits for quartz crystal oscillators (Miller oscillators).
The second is the matched PNP common-base pair Q3, Q4 that eliminates the undesirable Miller effect; it drives an active load Q7 plus matched pair Q5, Q6. That active load is implemented as a modified Wilson current mirror ; its role is to convert the (differential) input current signal to a single-ended signal without the attendant 50% losses ...

In effect, it is as though each capacitor charges and discharges through the resistance found in the circuit when the other capacitor is an open circuit. The open circuit time constant procedure provides the linear term in jω regardless of how complex the RC network becomes.
