摘要：
An oscillator is disclosed. The oscillator includes a first capacitor. The oscillator also includes a second capacitor. The oscillator further includes a first current source. The oscillator also includes a second current source. The oscillator further includes a comparator that has a first input and a second input. The oscillator also includes a reference node. The oscillator further includes a controller that is configured to selectively couple the first current source to the first capacitor and the second current source to the reference node during a first time period.
