Miller's theorem

Miller's theorem is a concept in electrical engineering used to simplify complex circuit analysis. When a capacitor connects between two points in a circuit with other components, it can create complicated interactions. Miller's theorem allows engineers to split this capacitor into two separate capacitors—one connected to each of the original points—and adjust their values accordingly. This simplifies the circuit analysis by breaking down the complex feedback effect into manageable parts, making it easier to understand, design, and analyze high-frequency circuits without changing their overall behavior.
