Abstract:
1. A signal-processing circuit, comprising: first and second inputs configured to receive first and second differential signals, respectively; a third input connected to a first end of a first resistor and configured to receive a common-mode signal, said first and second differential signals having substantially opposite phase with respect to each other; a first output connected to a second end of the first resistor and configured to supply a first processed signal; first formation means, coupled to said first output, for forming said first processed signal at said first output, which are configured to operate based on said first differential signal and said common mode signal; and second formation means, coupled to said first output, for forming said first processed signal at said first output, which are configured to operate based on said second differential signal and said common mode signal, said first and second formation means being configured to co-operate in forming said first processed signal, wherein each of said first and second formation means comprise a respective controlled current generator, the controlled current generators being controlled, respectively, by a respective one of said first and second differential signals, and configured to supply through said first resistor a unidirectional generator current having respective values that are a function, respectively, of a respective one of said first differential signal and of said second differential signal.
