ABSTRACT:
Systems and methods for on-chip signaling are disclosed. In some embodiments, an integrated circuit having on-chip signaling between a first component and a second component includes, a differential interconnect capable of coupling the first component to the second component, a driver capable of being coupled to the first component that sends data on the differential interconnect, a receiver capable of being coupled to the second component that receives the data, and a plurality of negative impedance converters capable of being coupled to the differential interconnect that provide loss compensation.
