  • Patent number: 11283462
    Abstract: A semiconductor device includes first and second terminals, a reference resister being coupled between the first and second terminals, third and fourth terminals, a sensor resister being coupled between the third and fourth terminals, a first buffer which supplies a first reference voltage to the first terminal, a second buffer which supplies a second reference voltage to the fourth terminal, a reference voltage generation circuit which supplies one of first and second voltages alternately in a time division manner as the first reference voltage and supplies the other as the second reference voltage, a first analog-to-digital conversion circuit which performs analog-to-digital conversion on a signal line coupled to the third terminal, an RC filter disposed on the signal line, a noise detector which detects noise of the signal line, wherein a time constant of the RC filter is changed based on a result of the noise detector.
