how does an analog to digital converter work?

Question

if someone could give a circuit and give a detailed explanation
especially the role of circuit components used therein?

Answer 1

An analog-to-digital converter (abbreviated ADC, A/D or A to D) is an electronic internal circuit (i/c) that converts continuous signals to discrete digital numbers. The reverse operation is performed by a digital-to-analog converter (DAC).Typically, an ADC is an electronic device that converts an input analog voltage ( or current ) to a digital number. The digital output may be using different coding schemes, such as binary and two's complement binary. However, some non-electronic or only partially electronic devices, such as rotary encoders, can also be considered ADCs

Answer 2

The input goes into a comparator that outputs a reference voltage if it's above this reference voltage and 0 if it's below. The output is amplified to give the first significant bit. The comparator output is then subtracted from the original input and sent to a second comparator with *half* the reference voltage of the first. Its output is amplified to give the second bit. And so on.
