What is the maximum conversion time for an ADC using a 12 bi

What is the maximum conversion time for an ADC using a 12- bit DAC and a 2- MHz clock frequency? What is the maximum possible number of conversions per second? How many resistors and comparators are required to implement a 10-bit flash ADC?

Solution

9)max conversion time 2^n/fC => 2^12/(2*10^6)   [n=no.of bits and fc= clock frequency]

                                           Tt    = 2.05msec

no.of conversions per second= 1/Tt= 488 conversions

10) no.of resistors = 2^n =2^10= 1024

     no .of comparators= 2^n-1 =1023
