ABSTRACT:
This flash analog-to-digital converter with integrating input stage has a very high speed and resolution due to drastically reduced number of components. The input signal is integrated for providing a varying ramp signal to comparators. A plurality of the comparator codes produced thereby is sampled, whereby a code sequence is established. A resistor or capacitor network determines quantization levels for the comparators so that the code sequence is different for any substantially different input signal. The code sequence is converted by means of an encoder, adder and decoder into the output code of the converter.
