Circuit arrangement including a common source sense-FET |
摘要 |
A current sensing circuit arrangement is disclosed. The circuit arrangement includes a load transistor for controlling a load current to a load being coupled to a drain electrode of the load transistor. A sense transistor is coupled to the load transistor. The sense transistor has a drain electrode that provides a measurement current representative of the load current. The load transistor and the sense transistor are field effect transistors having a common source electrode. A measurement circuit is configured to receive the measurement current from the sense transistor and to generate an output signal therefrom, the output signal being representative of the load current.
