Abstract
A zero-crossing amplifier unit for use in high speed analog-digital-converters. A gain stage compares a sampling voltage at an input node with a provided threshold voltage to obtain a gain stage output signal. A voltage controlled current source provides a load current depending on a time window between an initial slope and an end slope of the gain stage output signal. A slope control means increases a duration of a rise and/or fall time of at least one of the initial and end slopes of the gain stage output signal.
