摘要
设计了一种带预加重结构的低压差分信号(LVDS)串行发送器,改进了传统LVDS发送器的共模电平反馈控制结构。LVDS串行发送器采用双运放反馈控制电路,在避免集成大电阻的同时,能够更好地稳定差分信号的输出摆幅。采用电路预加重技术,克服了数据高速传输过程中的高频信号损失问题。基于0.25μm CMOS工艺,实现了LVDS发送器,芯片面积约为0.03mm2,可满足2.5 Gb/s的高速串行数据传输。
A low-voltage differential signal(LVDS)serial transceiver was designed with improved closed-loop feedback control structure and pre-emphasis.Using this circuit,output common-mode voltage could be controlled without large resistance.A pre-emphasis circuit was employed to overcome high frequency signal loss during transmission.Designed and implemented in 0.25 μm CMOS process,the transceiver,which occupies a chip area of 0.03 mm2,is applicable for 2.5 Gbit/s serial data transmission.
