Abstract
An LC tank circuit, such as an LC tank circuit of a step-tuned voltage controlled oscillator, includes an inductor and one or more capacitors. The inductor can be dog-bone shaped with a body, an extension and a chamfered joint to improve current distribution. The body and the extension can extend along different directions. The body can be narrower than the extension, and the extension can be sufficiently wide to interface with a plurality of switched capacitor circuits coupled to different parts of the extension.
