專利摘要(英)
A feed-forward equalizer and a voltage-mode signal transmitter using thereof are provided. The feed-forward equalizer (FFE) includes an output, a plurality of tap drivers, and a control circuit. Each tap driver includes a cell driver. The control circuit includes a FFE control loop and an output impedance control loop. The FFE control loop includes a first replica circuit corresponding to a portion of the plurality of cell drivers. The FFE control loop generates a plurality of first reference voltages according to the first replica circuit. The output impedance control loop includes a second replica circuit corresponding to the plurality of cell drivers in the FFE. The output impedance control loop generates a plurality of second reference voltages according to the first reference voltages and the second replica circuit. The tap drivers are controlled by the first and second reference voltages to adjust its own output impedance respectively.
