Fundamentals of Integrated Transformers: from Principles to Applications Video

Abstract: Integrated magnetic transformers are becoming ubiquitous in mm-wave and RF systems, while also finding application in fully integrated DC-DC converters. This tutorial will cover the fundamentals of transformer operation spanning from the underlying physical principles, to the link between the magnetic parameters (inductances and magnetic coupling) and the inductor geometry, to its use in the design of building blocks like LNAs, PAs, VCOs, etc. The advantages and possibilities of using a transformer for the implementation of baluns, impedance transformation networks, higher-order resonant networks, feedback circuits, etc. will be highlighted.
