This paper presents a complete characterization of single‐turn differentially driven high‐quality (Q) factor inductors at 10 GHz. The separate characterization of individual physical dimension through a series of 3D electromagnetic (EM) simulations allows us to evaluate their effects on the inductor's Q and inductance L separately. The results show that single‐turn inductors can generate Q greater than 20 at 10 GHz with inductance L at the sub‐nano Henry range. Finally, a lumped‐element equivalent circuit of the inductor was developed for predicting associated Q, L, and frequency behavior. © 2003 Wiley Periodicals, Inc.
