  • Programmable high-frequency high-gain equalizer for digital display interfaces
    Publication number: 20120188031
    Abstract: There is provided a programmable high-frequency high-gain equalizer for digital display interfaces comprising, two pairs of current sources; two pairs of transistors arranged as two differential pairs, each transistor connected to a different one of the current sources; and a pair of a negative impedance resistors connected to the two pairs of two differential pairs; and a pair of capacitive and programmable resistive degeneration connected to the two pairs of two differential pairs to optimize the equalizer gain.
