Explanation:
Detailed explanation-1: -Ramp converter ADCs generate a sawtooth (piece-wise linear ramp) voltage signal and use a comparator, integrator, and capacitor (sample/hold) network to discern the input voltage level. A clock governs the voltage ramp changes, and the time is noted when equality occurs.
Detailed explanation-2: -A delta-encoded or counter-ramp ADC has an up-down counter that feeds a DAC. The input signal and the DAC both go to a comparator. The comparator controls the counter.
