TWO STAGE FLASH ANALOG-TO-DIGITAL SIGNAL CONVERTER

A two-stage flash analog-to-digital signal converter has a first stage voltage divider network and a set of amplifiers that perform an initial interpolation. The initial interpolation results are directly coupled, i.e. no resistive or capacitive elements, to a second stage comprising a set of comparators having multiple inputs. The multiple inputs of the second stage comparators are weightily coupled to the first stage amplifiers in a manner so as to cause the second stage comparators to generate a digital representation of the analog signal.
