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. WebbParallel flash converters use a bank of comparators that compare the input voltage to a set of reference voltages across a resistor network. The voltages start at a value equal to that for one-half the least-signifi-cant bit (LSB) and increase in equal voltage incre-ments equivalent to one LSB for each comparator. As

Webb24 mars 2024 · Abstract: Flash ADC is the fastest analog to digital converter, also known as parallel ADC. It is ideal for applications requiring large bandwidth.
