Abstract
The disclosure relates to the acquisition of a binary analog signal at input of a digital integrated circuit after its range of voltage variation has been matched with that acceptable by the digital integrated circuit by means of a resistive divider bridge. It is usual to define the architecture of an ASIC digital integrated circuit on the basis of libraries of pre-characterized cells. The disclosed device is designed to increase the possibilities of choice open to the integrated circuit designer, in enabling him to one pre-characterized cell of a Schmitt trigger for its top switching threshold and another for its bottom switching threshold. It consists of a circuit comprising, at input, a bank of Schmitt triggers of different types, followed by a discrete-rendering logic circuit deducing the logic state of the binary input analog signal of the combination of the output states of the input Schmitt triggers.
