WebIn amplifier design, the Miller effect can cause a drastic decrease of amplifier gain when frequency increases known gain roll-off. So, the coupling impedance in these amplifiers is a parasitic capacitance. Thus, this is all about an overview of the miller theorem, derivation, proof, and its applications. Generally, this theorem is mainly used ...
WebIn electronics, a multi-transistor configuration called the Darlington configuration (commonly called a Darlington pair) is a compound structure of a particular design made by two bipolar transistors connected in such a way that the current amplified by the first transistor is amplified further by the second one.
