| 摘要 |
The present invention provides a system and a method for driving a differential signal which includes a differential data input, a plurality of switches coupled to a current source for steering current depending on the differential data input, a first differential output and a second differential output and a coupled to at least two of the plurality of switches and a first source follower and a second source follower coupled to the first differential output for controlling output impedance. This architecture prevents the common mode noise reflected from the driver from becoming a differential signal and meets the requirements of the LVDS and SubLVDS standard down till 1.62V. Also this architecture is capable of operating in Gbps range making it a high-speed differential driver with very low power.
