4 Bit Flash Adc Circuit Diagram. Fig 1 block diagram of flash adc design and analysis of low power 4 bit flash adc using quantum voltage comparator 45. Also called the parallel a d converter this circuit is the simplest to understand.
For an n bit converter the circuit employs 2 n 1 comparators. Instead of using the comparators in a flash adc only once during a ramp input signal the folding adc re uses the comparators multiple times. The circuit shown here is a four bit analog to digital converter adc.

Chirag patel gaurav yadav harvijay raj vijay sankar 4 bit flash adc 2. It is formed of a series of comparators each one comparing the input signal to a unique reference voltage. The block diagram of proposed quantum voltage comparator based 4 bit flash adc has been shown in fig 1. Instead of using the comparators in a flash adc only once during a ramp input signal the folding adc re uses the comparators multiple times.
