ABSTRACT:
An integrated circuit inductor may have upper and lower loop-shaped line portions that are connected in series. The upper and lower portions may have 45° bends that form hexagonal or octagonal loops. Each loop portion may have one or more turns. Intervening metal-free regions of metal routing layers may be formed between the two layers to reduce capacitive coupling. Each loop portion may have sets of two or more metal lines shorted in parallel by vias. The upper and lower loops may be laterally offset or nested to reduce capacitive coupling.
