The effect by which a capacitance between the input and output of an inverting amplifier appears (1 + gain) times larger from the input. It degrades the high-frequency response of common-emitter and common-source stages.
Field: Bipolar transistors
Input impedance is low, about 1/gm (about 26 Ω at 1 mA), and because the base is AC-grounded the stage avoids feedback capacitance between input and output (the Miller effect), so it amplifies to high frequencies.
Which is a characteristic of a common-base amplifier?In an inverting amplifier, the capacitor between input and output sees a voltage swing (1 + gain) times the input, so from the input it appears (1 + |Av|) times larger—the Miller effect, which for a MOSFET involves the gate-drain capacitance Cgd.
What is the effect in which the gate-drain capacitance appe…The overlap forms gate-to-source/drain overlap capacitance, which adds delay via the Miller effect.
