Flash Adc Circuit Diagram. A resistive divider with 2 n resistors provides the reference voltage. For a test set t a fault case d is equivalent to a fault case g if and only if the output response of the circuit of the two fault cases cannot be distinguished from each other.
B figure 2 block diagram of a previously known flash adc and a resistor ladder circuit. For a test set t a fault case d is equivalent to a fault case g if and only if the output response of the circuit of the two fault cases cannot be distinguished from each other. Flash adcs are made by cascading high speed comparators.
1 it is the fastest type of adc because the conversion is performed simultaneously through a set of comparators hence referred as flash type adc.
A block diagram of a flash adc. For an n bit converter the circuit employs 2 n 1 comparators. For a test set t a fault case d is equivalent to a fault case g if and only if the output response of the circuit of the two fault cases cannot be distinguished from each other. The reference voltage for each comparator is one least significant bit lsb greater than the reference voltage for the comparator immediately below it.
