<p>The present invention provides for a differential driver for transmitting a differential signal including: a first power source to supply a first voltage; a second power source to supply a second voltage that is less than the first voltage; a current steering circuit coupled between the first power source and the second power source, the current steering circuit for steering a current into either a positive differential output node or a negative differential output node to transmit the differential signal according to a data signal and a dataN signal; a resistor interposed between the first power source and the current steering circuit; and a constant current sink interposed between the current steering circuit and the second power source, the constant current sink for sinking the current having a substantially constant value, in which, the dataN signal is the inverse of the data signal.</p> |
