摘要： A circuit includes a first path including a first transistor and a first current source. The first transistor is responsive to a tuning voltage. The circuit also includes a tuning voltage range extension circuit responsive to the tuning voltage. The tuning voltage range extension circuit is configured to selectively change current supplied by the first path as the tuning voltage exceeds a capacity threshold of the first transistor.

摘要： A method includes tracking a tuning voltage at a first circuit coupled to a first drain node of a first supply of a charge pump. The method also includes tracking the tuning voltage at a second circuit coupled to a second drain node of a second supply of the charge pump. The method further includes stabilizing a first voltage of the first drain node and a second voltage of the second drain node responsive to the tuning voltage.
