Abstract
An apparatus for driving a load using a low supply voltage includes a voltage-mode driver and a current source arrangement. The voltage-mode driver provides a desired termination impedance and a first portion of a desired output current to the load. The current source arrangement provides a second portion of the desired output current. The desired output current generates a predetermined voltage swing across the load, while the voltage-mode driver and the current source arrangement are powered by the low supply voltage.
