The entire digital output word is present just after the propagation delay time of comparators and the encoding logic gates. Hence flash type adc is the fastest adc.
The circuit is found to be working satisfactorily.
The circuit diagram of a 3 bit flash type adc is shown in the following figure the 3 bit flash type adc consists of a voltage divider network 7 comparators and a priority encoder.
