<p>A voltage-mode differential driver (105) is disclosed. The differential driver (105) includes two driver arms (110-P, 110-N), each driver arm (110-P, 110-N) including a variable-impedance driver (116) for driving a single-ended output signal. Each variable-impedance driver (116) comprises multiple driver slices, where each driver slice includes a pre-driver circuit and a driver circuit. Advantageously, it has been determined that the disclosed voltage-mode driver design requires less power than conventional current-mode drivers. In one implementation, the disclosed voltage-mode driver design provides the capability of independently programming the delay of the two single-ended outputs so as to compensate for differential skew. Other embodiments and features are also disclosed.</p> |
