Pseudo-differential receiving circuit

A receiving circuit for signal transmission through p transmission channels in a known frequency band, p being an integer greater than or equal to 2, comprising:

• m signal terminals, a common terminal and a reference terminal, the signal terminals being intended to be connected to an interconnection having at least m transmission conductors, m being an integer greater than or equal to p;
• m differential circuits, each of the differential circuits having a first input terminal coupled to one and only one of the signal terminals, each of the differential circuits having a second input terminal coupled to a common node, the voltage between the common node and the reference terminal being mainly determined by the voltage between the common terminal and the reference terminal, each of the differential circuits having an output, the output signal of each of the differential circuits being, for small signals in a part of the known frequency band, proportional to the voltage between the signal terminal coupled to the first input terminal of said each of the differential circuits and the common terminal;
• and
• a combining circuit delivering, when the combining circuit is in the activated state, p output signals of the receiving circuit corresponding each to one of said p transmission channels, the output of each of the differential circuits being coupled to an input of the combining circuit, each of the output signals of the receiving circuit being mainly determined by a linear combination of the output signals of the differential circuits, at least one of the linear combinations being such that two or more coefficients of said at least one of the linear combinations are not equal to zero.
