Embodiment Construction
[0036] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.
[0037] Figure 7 A pre-emphasis device for a low-voltage differential signal transmitter according to an embodiment of the present invention is shown, including:
[0038] A pre-emphasis pulse signal generating unit 10 configured to generate a pre-emphasis pulse signal DPEM according to a serial data signal received from an external source;
[0039] And the pre-emphasis current output unit 20, which includes:
[0040] A bypass unit 22, which is connected in parallel with the LVDS driver 30, includes a bypass switch K configured to act in response to the pre-emphasis pulse signal, and bypass the additional current applied to the LVDS driver when it acts;
[0041] The additional current unit 24, which includes field effect transistors S4 and S5 forming a channel, the gates of the field effect transistors S4 and S5 are connected to an ...
