Webb5 feb. 2024 · ADC Comparison – Common Types of ADC Flash and Half (Direct Type ADC): Flash ADCs, also called “direct ADCs” are very fast—capable of sampling rates in the gigahertz range. They achieve these speeds by running a bank of comparators that operate in parallel, each for a defined voltage range. lawn mower repair in nicholasville kyWebbFlash ADC. Flash converters are so-called because they are the fastest type of ADC. Flash ADCs contain a chain of parallel comparators. They can be obtained with a limited precision only, are expensive and consume a considerable amount of pover. The output of the comparators is converted to binary form by combinational logic (a priority encoder). kanban and scrum - making the most of both

"WebbFlash ADCs are also prone to sporadic and erratic outputs known as "sparkle codes." Sparkle codes have two major sources: Metastability in the 2N-1 comparators, and thermometer-code bubbles. Mismatched comparator delays can turn a logical 1 into 0 (or vice versa), causing the appearance of "bubbles" in an otherwise normal thermometer … " - The parallel comparator/flash adc
