| Zusammenfassung: | PURPOSE: A method of forming a sensing circuit and a structure thereof are provided to display a current that has passed through a main transistor and a current that has passed through the drain of a main transistor and a sensing transistor. CONSTITUTION: A main transistor(25) has a source, a gate, and a drain. A detection transistor(21) comprises: a source region smaller than that of the main transistor; a gate connected to the gate of the main transistor; and a drain transistor connected to the drain of the transistor. A resistance divider is connected to the source of the main transistor. A first resistor has a first terminal connected to the input terminal of the resistance divider and also has a second terminal connected to a detection node. A second resistor has a second terminal connected to the first terminal and the detection node. |
