Patent ID: 7583122

Claim:
A signal receiver inserted between a first and a second voltage reference and having a first and a second input terminal effective to receive differential signals and an output terminal effective to provide a converted signal, wherein the signal receiver comprises a conversion stage inserted between said first and second voltage references and connected between said first and second input terminals of said signal receiver and an input terminal of a hysteresis comparator, connected to said output terminal of said signal receiver, said conversion stage performing a conversion from any input signal received on respective input terminals to an intermediate signal provided on an output terminal and suitable for reception by said hysteresis comparator; wherein the conversion stage further comprises: a first current mirror connected to said first voltage reference and to said input terminals, as well as to a bias terminal; a second current mirror connected to said second voltage reference and to said first input terminal, as well as to a circuit node; a third current mirror connected to said second voltage reference and to said second input terminal, as well as to said output terminal; and a fourth current mirror connected to said first voltage reference, to said circuit node, as well as to said output terminal.
