Abstract
An integrated circuit comprises at least one differential input stage. The differential input stage includes an input circuit and a shaping circuit. The input circuit comprises a first portion and a second portion for providing two pairs of differential signals. The propagation times of the first and second circuit portions are preferably substantially identical. The shaping circuit differentiates each of the two pairs of differential signals and combines them to obtain a single binary type of signal.
