    Hi .
    any know how to calibrate the noise level in CMOS devises???

    What kind of CMOS devices? CD4000 series logic, or 74HCxx, or what did you have in mind?

    Thanks for replying.
    I am working with CMOS image sensors.
    The doubt is I am using Iron 55 X-ray with 5.9KeV as a source..
    would like to validate the CMOS devices to measure this small amount of signal.
    whether it is validate to use.
    bcz if we get more noise instead of original signal, its waste of work.
    and also would like to hear calibration curve between the voltage and ADC out put.!!!!
