    Something got garbled in the explanation of photodiode action -
    The second sentence is incomplete and hard to make sense of.

    I saw your response to the other post asking about it. This is how we find the mistakes I guess. How would you word it?

    One suggestion:

    "Operation in this photovoltaic (PV) mode is not linear over a large dynamic range. At low frequencies (< 100 kHz) it is sensitive and low noise"

    Had a little trouble finding it, so here's the location...

    http://www.allaboutcircuits.com/vol_3/chpt_3/12.html

    Look for Photodiodes, 4th paragraph (second below the illustration).

    Was:
    The voltage out of a photodiode may be observed. However, operation in this photovoltaic (PV) mode is not linear over a large dynamic range. Though, it is sensitive and low noise at low frequencies, < 100 kHz.

    Maybe:

    The voltage out of a photodiode may be observed. Operation in this photovoltaic (PV) mode is not linear over a large dynamic range, though it is sensitive and has low noise at frequencies less than 100 kHz.

    ***************

    This area (Special Purpose Diodes) has several things needing updating, including my proposed Light Emitting Diode update. There is a lot happening behind the scenes. It seems folks have lives outside this site <gasp!>

    Thanks for the update to PD section. I have entered the change into the master copy at ibiblio.org

    I would say, "has low noise" or "contributes little noise" or "is a low-noise device".
