TL;DR: Synthesis of an Inductor is described using new EM solver to reduce the time required for the synthesis and modeling of the spiral inductor new tools has been developed which are fast and much more accurate.
Abstract: Spiral Inductors suffer from complex loss mechanism in the metal and substrate and consume large chip area making them difficult to characterize and expensive to implement. The performance of on chip spiral inductors is a limiting factor. The spiral inductor design space is complex and innovative optimization and synthesis techniques are required to maximize performance. Numerous analog circuits such as Low Noise Amplifiers (LNA), Voltage Controlled Oscillators (VCO) and on chip filters depend on inductors with optimized design parameters. Consequently, the modeling of automated design of spiral inductors is critical to the successful realization of mixed signal systems. RF/analog circuits depend on inductors with optimized design parameters to enhance performance of integrated spiral inductors is increased in the 100 MHz to 10 GHz range where the low frequency quality factor (omega l/r) of the inductor is large. To reduce the time required for the synthesis and modeling of the spiral inductor new tools has been developed which are fast and much more accurate. In this paper synthesis of an Inductor is described using new EM solver.
