  • Signaling over RC-dominated transmission lines
    Patent number: 12237878
    Abstract: The disclosure provides a signaling link that overcomes or at least reduces the limitations of RC-dominated signaling wires, improving both the bandwidth and the power consumption of signaling circuits. Both an AC and a DC signaling link are disclosed. In one example, a signaling link is provided that includes: (1) a transmitter including a passive equalizer, (2) an over-terminated receiver, and (3) a lossy channel having a first end connected to the passive equalizer and a second end connected to the receiver, wherein the lossy channel has a channel characteristic impedance that is lower than a terminating impedance of the passive equalizer and a termination impedance of the receiver.
    Type: Grant

  • Proportional AC-coupled edge-boosting transmit equalization for multi-level pulse-amplitude modulated signaling
    Patent number: 10623217
    Abstract: A PAM signaling system utilizes multiple equalizers on each data lane of a serial data bus, each of the equalizers associated with a different signal eye of the serial data bus.
