My research team has a very broad focus in this arena, ranging from materials, to devices, to circuits, to systems, and including: fundamental device theory, the understanding of broadband noise and linearity, profile optimization for a given circuit metric, 2-D/3-D device-level simulation and TCAD, compact modeling, cryogenic operation, and radiation effects. We are particularly interested in the fundamental understanding of how device-level engineering (with SiGe) couples to mixed-signal circuit-level performance (i.e., device-circuit interactions).
