Miller effect examples (high-frequency model of a MOSFET) - clearly explained In this video, we explore the high-frequency small-signal model of a MOSFET, focusing on how its parasitic capacitances are formed and how they impact circuit performance. Step by step, we analyze two amplifier examples—a common-source MOSFET amplifier and a cascoded MOSFET amplifier using a resistor as the current source. You’ll learn which internal capacitances can be ignored, which can be combined, and which ones ex
