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