“…With newly emerging wireless communication demands, such as 5G, the realization of fully integrated systems with on-chip components is critical to reduce production costs and overall device size. Along these lines, the integration of many passive devices like inductors, capacitors and transformers is very important, since they serve as the fundamental building blocks of many RF integrated circuits (RFICs) and their performance largely affects the overall circuit specifications [1,2,3,4,5,6,7,8]. Fortunately, the evolution of microelectronic process technologies has allowed, to a large extent, the fabrication of active and passive components on the same chip.…”
