    Depletion MOSFET Flicker Noise

    Hi all,

    When operating in saturation, subthreshold, or weak inversion, which MOSFET type has lower flicker noise: enhancement-mode or depletion-mode? Intuitively, the depletion FET should have lower flicker noise because the E-field within the gate oxide pushes carriers away from interfacial traps at the surface. Is there any data or other solid information on this topic?

    Thanks

    You might expand your searching to include "buried channel
    MOSFET" which has been around for many decades, and
    for the reason you're after.
