A current sensor to be connected in series with a power semiconductor device between a voltage supply terminal and ground. The current sensor includes a first terminal to be coupled to the power semiconductor device, a second terminal to be coupled to one of the voltage supply terminal and ground, and a current mirror. The current mirror includes a first MOSFET and a second MOSFET each having a source, a drain, and a gate. The source of the first MOSFET is connected to the source of the second MOSFET and to the second terminal, the drain of the first MOSFET is connected to the first terminal, and the gate of the first MOSFET is connected to the gate of the second MOSFET. |
