Zusammenfassung:Embodiments of single-ended and differential output driver circuits include one or more complementary data switch pairs, each coupled to a T-coil. Each complementary data switch pair is coupled between a voltage source and a ground reference node, and each complementary data switch pair includes complementary transistors, each with a control terminal, a first current conducting terminal, and a second current conducting terminal. In each pair, the first current conducting terminals of the complementary transistors are coupled together at an output node, and the control terminals of the complementary transistors are configured to receive an input signal. A T-coil is coupled to the output node, and includes a first coil coupled between the output node and an output terminal, and a second coil coupled between the output node and a termination. A mutual inductance is present between the first and second coils during operation of the output driver circuit.
