Counter ramp adc conversion time

  1. Dec 9, 2011 #1
    I know that the conversion time for an adc counter ramp is the time between the start and stop of the signal conversion, but how do i calculate this time? Also is the conversion time for the bi-directional counter ramp adc 1/2 that of the uni-directional counter ramp adc? Could someone kindly provide me with some formulas of helpful literature? Any help will be greatly appreciated.

    Welcome to the PF.

    The wikipedia article on ADCs is a pretty good introduction:

    http://en.wikipedia.org/wiki/Analog-to-digital_converter

    Although I didn't see Dual-Slope ADCs mentioned there. (I could have missed it though.)

    Ah, it's in a separate article at wikipedia:

    http://en.wikipedia.org/wiki/Integrating_ADC

    .
