Abstract
A time-domain voltage comparator for an analog-to-digital converter includes a first voltage-to-time converter configured to be connected in series with at least one time delay cell and convert an input voltage into time information; a second voltage-to-time converter configured to be connected in series with at least one time delay cell and convert an input voltage into time information; and a phase comparator configured to determine a difference between times outputted from the first voltage-to-time converter and the second voltage-to-time converter.
