Original Abstract Submitted

A circuit includes a resonator, a transistor pair, and a common-mode feedback circuit. The transistor pair is cross-coupled across the resonator. The common-mode feedback circuit is coupled to the transistor pair. The common-mode feedback circuit includes first and second degeneration cells. The second degeneration cell is connected in parallel with the first degeneration cell. The second degeneration cell is configured to switchably vary a current flow through the transistor pair.
