1. A system comprising:

  • a transmitter;

    a receiver; and

    a transmission line coupled to the transmitter and the receiver;

    the receiver including;

    an amplifier; and

    a delay and gain circuit coupled to an output of the amplifier, whereinan output of the delay and gain circuit is fed back to the amplifier;

    wherein the amplifier includes a first, a second and a third pMOS transistor and a first, a second and a third nMOS transistor;

    wherein a gate of the first pMOS transistor and a gate of the first nMOS transistor are coupled to an input of the amplifier;

    wherein a gate of the second pMOS transistor and a gate of the second nMOS transistor are coupled to a drain of the first pMOS transistor and a drain of the first nMOS transistor; and

    wherein a gate of the third pMOS transistor and a gate of the third nMOS transistor are coupled to an inverse input of the amplifier.
