Abstract
A digital-to-analog converter includes a plurality of 1-bit elements each of which outputs a current corresponding to a value indicated by a digital signal when the digital signal is input; and a capacitive load connected to the plurality of 1-bit elements, the digital-to-analog converter being configured to generate an analog voltage waveform via the capacitive load that receives currents output from the plurality of 1-bit elements, wherein each of the 1-bit elements includes a switching circuit to change a bias of a voltage in each of the 1-bit elements according to a value indicated by an input digital signal, and to switch connection and non-connection with a power supply according to a change in the bias.
