LVDS低功耗高速驱动电路设计

Dsign of Low-power High-speed LVDS Driver Circuit

目前现存的LVDS驱动不能在低供电电压下工作,双电流源(DCS)LVDS驱动和开关电流源(SCS) LVDS驱动等两种新驱动适用于低电压应用。同时,这两种驱动大大减少了功耗以及器件尺寸,并且可以以超过1 Gb/s的速度传输数据。在高速数据采集系统中,有很好的应用前景。

While the previously reported LVDS drivers cannot operate with low-voltage supplies, two new LVDS drivers are proposed-double current sourees（DCS）LVDS driver and the switchable current sources（SCS）LVDS driver are suitable for low-voltage applications. Both drivers can reduce power consumption and dimensions, also, they can operate at date rates up to Gb/s. In the future, they might be used in the high-speed data acquisition system.
