In an N bit flash ADC, the analog voltage is fed simultaneously to 2^N− 1 comparators. The output of the comparators is then encoded to a binary format using digital circuits. Assume that the analog voltage source V_in(whose output is being converted to digital format) has a source resistance of 75 Ω as shown in the circuit diagram below and the input capacitance of each comparator is 8 pF. The input must settle to an accuracy of 1/2 LSB even for a full scale input change for properconversion. Assume that the time taken by the thermometer to binary encoder is negligible. If the flash ADC has 8 bit resolution, which one of the following alternatives is closest to the maximum sampling rate?
