ABSTRACT:
A digital-to-analog converter converts a digital input signal into an analog signal. The digital-to-analog converter includes: a power-supply unit for outputting voltages of different magnitudes through plural output terminals thereof; plural switches connected to the plural output terminals, which are controlled on and off, and are for applying the output voltages of the power-supply unit or a ground voltage to a next stage; and plural source transistors connected to the plural switches for outputting currents of magnitudes corresponding to the voltages applied from the respective connected switches of the plural switches. The plural source transistors are designed to have the same operating characteristics, thereby improving glitch characteristics.
