Abstract
A conversion and folding circuit includes a voltage-to-delay converter block, including preamplifiers, for converting a voltage signal into delay signals, and a folding block, including logic gates coupled to the preamplifiers, for selecting earlier-arriving and later-arriving ones of the delay signals. If desired, the logic gates may include odd and even chains for outputting delay signals to first and second analog-to-digital converters. If desired, the conversion and folding circuit may include first and second chains, and a chain selection circuit for selectively outputting a delay signal from a desired one of the first and second chains.
