摘　　要：介绍了一款高速串行接口发送机芯片。均衡器采用多抽头前馈均衡结构,且各阶均衡系数均可调,增大了均衡调谐范围,提高了均衡精确度;驱动器采用H树型电流模结构,提高了电流利用率,降低了功耗。设计采用TSMC 55 nm CMOS工艺,电源电压为1 V,输出数据率范围为550 Mb/s^6.25 Gb/s。在最高工作速率6.25 Gb/s下,发送机整体功耗约20 m W,结果表明发送机均衡精确度较高,功耗较低。A high speed serial interface transmitter chip is described. The equalizer adopts the multi-tap feed forward equalizer structure and the tuning coefficient of each tap can be adjusted, which increases the range of the balanced tuning and improves the balance precision. H-tree driver is utilized to transmit the serial signal, which improves the current utilization coefficient and reduces the power consumption. The transmitter is designed in TSMC 55 nm CMOS technology with 1 V power supply, and the output data rate range is from 550 Mb/s to 6.25 Gb/s. The overall power consumption is approximately 20 m W at the highest rate of 6.25 Gb/s. The results indicate that the transmitter possesses high balance precision and low power consumption.
