Abstract
Apparatus and methods for switch-coupled oscillators are disclosed. In certain implementations, an oscillator system includes a primary oscillator, one or more auxiliary oscillators, one or more switching circuits, and an oscillator control circuit. The oscillator control circuit can be used to control the one or more switching circuits to selectively couple the primary oscillator to all or a portion of the one or more auxiliary oscillators. The oscillator control circuit can also disable any auxiliary oscillators that are decoupled from the primary oscillator to reduce power consumption. By selecting a number of auxiliary oscillators to couple to the primary oscillator, the oscillator system can have a configurable phase noise versus power consumption profile.
