D/A converter, circuit device, oscillator, electronic apparatus and moving object
Abstract:
A D/A converter includes a decoder, a voltage selection circuit, and a voltage selection circuit. The voltage selection circuit includes a plurality of stages of selector blocks in which output of a selector of the selector block at the previous stage is input to a selector of the selector block at the subsequent stage. A plurality of voltages are input to the selector block at the first stage, and the selector block at the final stage outputs a D/A-converted voltage. Each of the plurality of stages of selector blocks includes a plurality of transistors and, of the plurality of transistors forming the selector block, a second transistor on a far side from a power source node is set to a lower threshold voltage than that of a first transistor on a near side from the power source node.
