Webb15 mars 2024 · As in flash ADC, as all the comparators compare the input simultaneously, so it is also known as the parallel ADC. And due to the parallel conversion, it is fastest among all other ADCs. WebbFlash 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).

WebbFlash analog-to-digital converters, also known as parallel ADCs, are one of the fastest way to convert an analog signal to a digital signal. Flash ADCs are ideal for applications requiring very large bandwidth, but they consume more power than other ADC architectures and are generally limited to 8-bit resolution. WebbA ‘flash converter’ consists of a number of analogue comparators, each set to trigger at a different one of these thresholds. An input voltage V will therefore trigger all the comparators that have threshold voltages less than V, and will not trigger the rest of the comparators that have thresholds greater than V.
