SEMICONDUCTOR SYSTEM AND METHOD FOR MANUFACTURING AND OPERATING THEREOF 

WIPO Patent Application WO/2024/065625

A1

A semiconductor system (1) and its manufacturing and operating method are disclosed. The semiconductor system (1) includes a clamping circuit (104), a first filter (110), a second filter (120), a first operational amplifier (OP) (130) and a second OP (140). The clamping circuit (104) is connected to a first terminal (100a) of a semiconductor device (100) to prevent the semiconductor device (100) from interference. The first filter (110) is connected to the clamping circuit (104). The first OP (130) is connected to the first filter (110). The first OP (130) is configured as a differential OP to generate a first output voltage (136), so that a voltage drop across a measurement resistor (150) is excluded and an on-state voltage drop across the semiconductor device (100) is measured. The second filter (120) is connected to a second terminal (100c) of the semiconductor device (100). The second OP (140) is connected to the second filter (120). The second OP (140) is configured to generate a second output voltage (146) so as to measure the current flowing through the semiconductor device (100). The first output voltage (136) and the second output voltage (146) are configured to measure an on-resistance of the semiconductor device (100).
