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.
