Abstract: 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.

Abstract: A method can include generating a first set of sample values for input variables in accordance with a prescribed set of probability distributions, running a set of simulations on an electronic component based upon the first set of sample values, multiplying the standard deviations of the original distributions by a scaling factor ?, generating a second set of sample values for the input variables based on the probability distributions thus generated, and running a set of simulations on the electronic component based on this second set of sample values. The method can also include the generation of Q-Q plots based on the data from the first and second set of simulations and data from a truly normal distribution or the distribution obeyed by the independently varying input parameters; and the use of these plots for assessment of the robustness and functionality of the electronic component.
