  • Patent number: 11778731
    Abstract: A multi-layer printed circuit board having a first landing pad in a first layer and along a first axis arranged to receive a positive signal and a second landing pad in the first layer and along a second axis that is spaced away from the first axis longitudinally in the first layer and where the second landing pad arranged to receive a negative signal. A first buried in a second layer and along the first axis is spaced away from the first landing pad along the first axis. A second buried in the second layer and along the second axis is spaced away from the second landing pad along the second axis. A first signal connector provides a first electrical connection between the first landing pad and the second buried via and a second signal connector provides a second electrical connection between the second landing pad and the first buried via.

  • Patent number: 11374541
    Abstract: A common-mode rejection receiver including a first differential amplifier arranged to receive a differential signal including receiving a positive signal of the differential signal at a first non-inverting input port and receiving a negative signal of the differential signal at a first inverting input port, and output a first differentiated signal based on a voltage differential between the positive signal and the negative signal. A clamping circuit is arranged to limit a magnitude of the first differentiated signal to a pre-determined limit. A second differential amplifier is arranged to receive the positive signal at a second inverting input port and receive the negative signal at a second non-inverting input port, and output a second differentiated signal. A matching circuit is arranged to receive the second differentiated signal output and output a matched signal. A summing circuit adds the clamped signal and matched signal and outputs a receiver output signal.
