WebMar 17, 2024 · One simple and easy way is by using parallel encoding, also known as flash, simultaneous, or multiple comparator converters in which comparators are used to detect different voltage levels and output their … A flash ADC (also known as a direct-conversion 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. Often these reference ladders are constructed of many resistors; however, modern implementations show that capacitive voltage division is also possible. The output of these comparators is generally fed into a digital encoder, which converts the input…
