Design of Compact Passive Components for RF and Millimeter-Wave Integrated Circuit in Silicon

Tight integration of high quality on-chip passive components poses significant challenges due to the complicated electromagnetic coupling between components and to interconnects in close proximity. Traditionally, a large separation distance is required to reduce the effects of parasitic coupling, wasting valuable silicon area and, hence, increasing cost. A large separation of components sometimes also requires longer interconnects, which introduce additional parasitics and degrade circuit performance. The goal of this research is to design/optimize compact integrated passive RF and mm-Wave devices in silicon. In this work, we propose compact inductors layout topologies achieving negligible magnetic coupling between two inductors without degradation of individual inductor performance by leveraging our magnetic flux management techniques. For validating the practicality of our layout methodology, output matching network redesign for a 5GHz PA IP block and ultr! a-compact integrated lumped-element coupled-resonator filter design are proposed. Both designs have been verified through full-wave EM simulation as well as on-wafer measurement of fabricated test chips.
