Abstract

The tunability of an inductor using an additional conductor segments with optical switching is presented. When the additional conductor is in the horizontal plane of the spiral inductor, a two‐turn spiral‐inductor tunability of 30% can be obtained. The tunability is reduced when the number of turns of the spiral is increased. The tunability can be further improved over the horizontal position by choosing an additional conductor segment structure above the spiral inductor (that is, in the vertical plane). The tunability of the inductor can be improved by 54% as compared to the horizontal tuning for a high number of turns of the spiral inductor (N = 6). This analysis was carried out using the TSMC 0.18‐μm 1P6M process. © 2005 Wiley Periodicals, Inc.
