Flash Type Adc Circuit Diagram. V ref is a stable reference voltage provided by a precision voltage regulator as part of the converter circuit not shown in the schematic. This is also called as flash adc.
A resistive divider with 2 n resistors provides the reference voltage. The flash type converter is the simplest and the fastest type of analogue to digital converter. However modern implementations show that capacitive voltage division is also possible.
The circuit is found to be working satisfactorily.
This is also called as flash adc. A flash adc is a type of analog to digital converter that uses a linear voltage ladder with a comparator at each rung of the ladder to compare the input voltage to successive reference voltages. The entire digital output word is present just after the propagation delay time of comparators and the encoding logic gates. Figure 1 shows a typical flash adc block diagram.
