Digital-to-Analog Conversion Circuit

Abstract

A digital-to-analog conversion circuit having high resolution is constituted by including a quantum Hall element having a resistance value R, a quantum Hall element pair having a resistance value 2R, a quantum Hall element connected to a node between the quantum Hall element and the quantum Hall element pair, and a switch which supplies any of a plurality of voltages (input voltage or ground voltage) having different values to a terminal different from a terminal of the quantum Hall element of a side connected to the node, in which at least a part of the quantum Hall element, the quantum Hall element pair, and the switch is used as a quantum Hall element whose resistance value is quantized by applying a magnetic field.
