D/A conversion circuit, oscillator, electronic apparatus, and moving object

摘要

A D/A conversion circuit includes a plurality of resistors that are connected to each other in series, and a plurality of MOS transistors that are connected to terminals of the plurality of resistors, respectively. The plurality of resistors and the plurality of MOS transistors are formed on a semiconductor substrate. Each of the plurality of resistors is constituted by a resistive element and a plurality of contacts provided in the resistive element. The plurality of MOS transistors are disposed so that a plurality of virtual straight lines that pass through each of the plurality of contacts and are perpendicular to a longitudinal direction of the resistive element pass between gate electrodes of two adjacent MOS transistors, when seen in a plan view of the semiconductor substrate.
