    摘要： A circuit includes a current source having at least first terminal and a second, control terminal. The current source is configured to receive a current control signal at the control terminal and in response thereto generates a first current signal at the first terminal. The current control signal controls a current level of the first current signal. The circuit also includes at least one sensing element responsive to one or more sense parameters and having an input adapted to couple to the first terminal of said current source. The sensing element is configured to receive one or more current signals comprising at least the first current signal and in response thereto generates a sensed output signal at an output thereof. A corresponding method for operating the circuit is also provided.
