Design a 2 line to n bit binary converter suitable for a Fla

Design a 2\" line to n bit binary converter suitable for a Flash A-toD converter with 32 levels. How many gate delays are there from the comparator outputs to the binary outputs?

Solution

The number of gate delays from the comparator outputs to the binary outputs is equal to the number of bits required for 32 levels.

2^n = 32

2^n = 2^5

n=5 bits

So, the number of gate delays required are 5.
