Title:
DIGITAL-ANALOG CONVERSION CIRCUIT
Document Type and Number:
WIPO Patent Application WO/2023/021576
Kind Code:
A1
Abstract:
In the present invention, a high resolution digital-analog conversion circuit comprises: a quantum Hall element 31 having a resistance value R; a quantum Hall element pair 32a having a resistance value 2R; a quantum Hall element 31b connected to a node N1 between the quantum Hall element 31 and the quantum Hall element pair 32a; and a switch 33 that supplies one of a plurality of voltages of different values (input voltage or ground voltage) to a terminal different from the terminal on the side connected to the node N1 of this quantum Hall element 31b. At least some of the quantum Hall element 31, the quantum Hall element pair 32a, 32b, and the switch 33 are used as a quantum Hall element whose resistance value is quantized by applying a magnetic field.
