Disclosed is a current-steering digital-to-analog converter (DAC) which comprises a decoder for receiving an N-bit digital input signal and converting the same into first and second (N&#x2212;1)-bit digital signals, M (=2) current cells for supplying the current based on the two digital signals, a current cell driver for generating a first analog voltage and a second analog voltage corresponding to the currents based on the two (N&#x2212;1)-bit digital signals by control of a first clock signal and a second clock signal, and an amplifying circuit for sampling and holding the first and second analog voltage with reference to the first and second clock signals to generate a glitch-removed signal.
