ABSTRACT:
This multi-flash analog-to-digital converter (ADC), in particular dual flash ADC, has extremely high speed and resolution. The final resolution of a comparator/multiplexer section can be effectively doubled. For instance, a 16-bit ADC can employ 300 rather than 255 comparators. A monolithic integration can be accomplished.
A resistive network is coupled to a reference source for providing a plurality of reference signals. A comparator/multiplexer section compares a comparison signal against the reference signals, selects one of the reference signals and produces a code. A capacitor circuit provides the comparison signal in response to the ADC input signal and subsequently in response to a signal difference between the stored ADC input signal and selected reference signal. Two codes are encoded and converted into the output code of the ADC.
