ABSTRACT:
A low voltage differential swing driver circuit comprises first and second serially connected field effect transistors connected in series through first and second resistors. Third and fourth field effect transistors are serially connected together through third and fourth resistors. A diode connects one side of each of the serially connected transistors to one side of a source of regulated low voltage. A remaining side of the regulated low voltage source is connected to a remaining side of the serially connected transistors whereby differential currents are produced through the pairs of transistors. A voltage bias source is connected to a junction of said first and second resistors and to the junction of said third and fourth resistors. Control logic supplies a data switching signal to a gate of the first and fourth transistors, and a complementary data switching signal to a gate of said second and third transistors. A differential signal is produced between said junctions which are connected to first and second transmission lines.
