Abstract
Official abstract text for this publication.
An electronic device includes an inductive element, and variable capacitors. Each variable capacitor includes: first and third capacitors, both having a first terminal electrically connected to a first terminal of the inductive element; and second and fourth capacitors, both having a first terminal electrically connected to a second terminal of the inductive element. A first switch circuit electrically connects or isolates a second terminal of the first capacitor to/from a second terminal of the second capacitor. A second switch circuit electrically connects or isolates a second terminal of the third capacitor to/from a second terminal of the fourth capacitor. A third switch circuit electrically connects or isolates the second terminal of the first capacitor to/from the second terminal of the fourth capacitor. A fourth switch circuit electrically connects or isolates the second terminal of the third capacitor to/from the second terminal of the second capacitor.
