VOLTAGE MODE TRANSMITTER

摘要

A voltage mode transmitter includes a resistive network and a de-emphasis value controller. The resistive network receives plural input voltages and provides plural weighting values corresponding to respective input voltages. A sum of the products of the plural input voltages and the corresponding weighting values is equal to an output voltage. The de-emphasis value controller receives a first signal. After the first signal is inverted as an inverted first signal and the inverted first signal is delayed for a time period, the de-emphasis value controller generates a second signal. The de-emphasis value controller further receives a value control signal. At least one of the plural input signals is provided by the first signal and at least one of the plural input signals is provided by the second signal according to the value control signal.

1. A voltage mode transmitter, comprising:
a resistive network receiving plural input voltages and providing plural weighting values corresponding to respective input voltages, wherein a sum of the products of the plural input voltages and the corresponding weighting values is equal to an output voltage; and a de-emphasis value controller receiving and converting a specific signal to a first signal and a second signal, wherein there is a phase difference between the second signal and an inverted first signal; wherein the de-emphasis value controller further receives a value control signal, wherein at least one of the plural input signals is provided by the first signal and at least one of the plural input signals is provided by the second signal according to the value control signal.
