Patent ID: 8902998

Claim:
A receiver of a near-field multichannel transmission system providing m transmission channels each corresponding to a signal to be sent from a first monolithic integrated circuit to a second monolithic integrated circuit, where m is an integer greater than or equal to 2, the first monolithic integrated circuit and the second monolithic integrated circuit being structurally combined, the receiver comprising: n coupling devices built in the second monolithic integrated circuit, where n is an integer greater than or equal to m; and a multiple-input-port and multiple-output-port amplifier, said multiple-input-port and multiple-output-port amplifier being built in the second monolithic integrated circuit, said multiple-input-port and multiple-output-port amplifier having n input ports and m output ports, each of said input ports being connected to one and only one of said coupling devices, each of said coupling devices being connected to one and only one of said input ports, said multiple-input-port and multiple-output-port amplifier having, when said multiple-input-port and multiple-output-port amplifier is in the activated state, for small signals, at each frequency in a frequency band used for transmission, a short-circuit transfer admittance matrix, said short-circuit transfer admittance matrix being a complex matrix of size m×n, two or more entries of each row of said short-circuit transfer admittance matrix being different from zero.
