Abstract：
The invention relates to a high-speed and low-power-consumption PAM4 transmitter used for high-speed serial interfaces, which belongs to the field of analog circuit design. The transmitter is operated based on the PAM4 encoding. In a 8: 2 combiner wherein 8 parallel paths of data are synthesized into 2 paths of data, a 4: 1 combiner is adopted instead of a 8: 4 and 4: 2 two-stage 2: 1 combiner. Therefore, the combiner and corresponding clock link structure is simplified, and the power consumption and the area are greatly saved.
