專利摘要(英)
A feed-forward equalizer (FFE) and a voltage-mode signal transmitter using the same are provided. The 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 impedance control loop. The FFE control loop includes a first replica circuit corresponding to a part of the cell drivers. The FFE control loop generates at least one first reference voltage according to the first replica circuit. The impedance control loop includes a second replica circuit corresponding to the cell drivers in the tap drivers. The impedance control loop generates at least one second reference voltage according to the first reference voltage and the second replica circuit. The tap drivers are controlled by the first and second reference voltages to adjust respective output impedance thereof.
