Advanced Circuit Techniques Using Integrated Transformers

Integrated magnetic transformers are becoming ubiquitous in mm-wave and RF systems, such that their co-design with active circuits is key. This talk will focus on the use of transformers in the design of building blocks like LNAs, PAs, VCOs, etc. The advantages and possibilities of using a transformer for the implementation of baluns, power combiners, impedance transformation networks, higher-order resonant networks, etc. will be highlighted. Particular attention will be paid to techniques for the co-design of the transformer and the active circuit.
