Abstract
A bias circuit can generate one or more bias outputs for a crystal oscillator. The bias circuit can include a first current mirror, a second current mirror, and a third current mirror. A capacitor can be coupled between the second and third current mirrors. In operation, a first bias output can be generated by the third current mirror, and a second bias output can be generated by the second current mirror. The first and second bias outputs can be coupled to a crystal oscillator.
