3 Bit Flash Adc Circuit Diagram. The circuit shown here is a four bit analog to digital converter adc. Following this analog circuit would be a digital decoder to go from the comparator outputs to a 3 bit binary number.
As the analog input voltage exceeds the reference voltage at each comparator the comparator outputs will sequentially saturate to a high state. Introduction an analog to digital converter a d or adc produces a. A resistive divider with 2 n resistors provides the reference voltage.
Explain why we must use a priority encoder to encode the comparator outputs into a four bit binary code and not a regular encoder.
In this circuit the. A flash type adc produces an equivalent digital output for a corresponding analog input in no time. Specifically it is a flash converter so named because of its high speed. My favorite resource for learning more about flash a.
