Abstract
An apparatus and method is disclosed for transmitting signals over a signal conductor using a precompensated driver that does not use a current source, and which drives the signal conductor with an impedance similar to the characteristic impedance of the signal conductor. Since no current source is used, the precompensated driver can operate at very low supply voltage.
