Abstract:
1. A signal transmitter, comprising: a checking circuit, arranged for checking a plurality of successive data bits to be transmitted and accordingly generating a checking result, wherein the plurality of successive data bits are compared to detect occurrence of a transition edge; and a driving circuit, arranged for referring to the checking result and transmitting a specific data bit with a plurality of different predetermined voltage levels, wherein the different predetermined voltage levels are successively outputted from the driving circuit; wherein when the specific data bit has a binary value equal to zero, the different predetermined voltage levels include at least a first nominal voltage level designated for transmitting the specific data bit and a boosted voltage level higher than the first nominal voltage level, and the driving circuit applies compensation to transmission of the specific data bit by outputting the first nominal voltage level prior to outputting the boosted voltage level; and wherein when the specific data bit has a binary value equal to one, the different predetermined voltage levels include at least a second nominal voltage level designated for transmitting the specific data bit and a degraded voltage level lower than the second nominal voltage level, and the driving circuit applies compensation to transmission of the specific data bit by outputting the second nominal voltage level prior to outputting the degraded voltage level.
