A digital-to-analog converter circuit is configured to convert an m-bit digital signal into an analog signal. The circuit includes a bit voltage generator convert each bit of segmented n-bit units of the digital signal into a first voltage or a second voltage, first capacitors each configured to store the voltage for each bit output from the bit voltage generator, switches connected to the first capacitors, a second capacitor connected to the switches, an output unit configured to output the voltage stored in the second capacitor as an analog signal, and a control unit configured to control the switches, connect in parallel the first capacitors with the second capacitor, and adjust the voltage stored in the second capacitor. |
