Direct-conversion ADC/Flash type ADC

This process is extremely fast with a sampling rate of up to 1 GHz.

Direct-conversion ADC/Flash type ADC:




This process is extremely fast with a sampling rate of up to 1 GHz. The resolution is however, limited because of the large number of comparators and reference voltages required. The input signal is fed simultaneously to all comparators. A priority encoder then generates a digital output that corresponds with the highest activated comparator.
