An electron-multiplying CCD adds a high-field multiplication register before the output amplifier. <Impact ionization> generates a large mean gain, reducing input-referred <read noise> but adding <multiplication excess noise>.


Electron-multiplying CCD

{wiki}

An energetic charge carrier creates an additional electron–hole pair. In a multiplication register this is stochastic, so the output charge fluctuates even when the input electron number is fixed.
