ABSTRACT:
A low-voltage differential signal driver for high-speed digital transmission includes a first converter operable to receive a signal in a first type and convert the signal into a second type, wherein a resistance of the first converter is variable. A second converter couples to the first converter, the second converter is operable to receive a signal in the second type and convert the signal into the first type, wherein a resistance of the second converter is variable. The driver is operable to scale the resistance of the first and second converters to provide a constant ratio between the resistance of the first and second converters.
