As the analog input voltage exceeds the reference voltage at each comparator, the comparator outputs will sequentially saturate to a high state. Young A. 2] In addition to the CML implementation, the comparator array and the encoder are fully pipelined. This is needed for many ADC types (like successive approximation ADC), but for Flash ADC's there is no real need for this, because the comparators are the sampling devices. It can be explained with the example of weight and a balance. The time duration of the gate opening is proportional to the input analog voltage. Therefore, the analog voltage is converted into time and the time counts represent the magnitude of the voltage(digital value). it is non-volatile memory. bit 23MS/s ADC, based on this new architecture, is designed and tested. Flash ADCs are expensive. The biggest disadvantage of the oversampling ADC is the output is delayed greatly due to a digital filter at the output stage.
