Flash Adc Circuit Diagram. The reference voltage for each comparator is one least significant bit lsb greater than the reference voltage for the comparator immediately below it. As the analog input voltage exceeds the reference voltage at each comparator the comparator outputs will sequentially saturate to a high state.
