Type-II charge-pump (CP) phase-locked loop (PLLs) are used extensively in electronic systems for frequency synthesis. Recently, a passive sampled loop filter (SLF) has been shown to offer major benefits over the conventional continuous-time loop filter traditionally used in such PLLs. These benefits include greatly enhanced reference spur suppression, elimination of CP pulse-position modulation nonlinearity,...
MOS device aging caused by hot-carrier injection (HCI) and negative/positive bias-temperature instability (N/PBTI) is increasingly more responsible for IC reliability failure for advanced process technology nodes. Accurate aging modeling and fast yet trustable reliability signoff are thus mandatory in process development and circuit design. This paper will first present an aging model that takes into...
Model-eliciting activities (MEAs) are a class of interdisciplinary problems designed to simulate authentic, client-driven situations in classroom settings. MEAs allow teachers and researchers to observe student development of conceptual models by requiring students to make their models explicit through design-test-revise cycles. Here, we present a method for assessing the design of MEAs and the learning...
A library of components for simulation and analysis of large vehicular electrical power systems using Modelica language is presented. Components are described using different levels of model complexity, catering for both detailed high fidelity transient switching dynamics and averaged value descriptions which, being time invariant, are a computationally efficient and useful tool for design, stability...
