Patent ID: 7030799

Claim:
A current-steering digital-to-analog converter (DAC) comprising: a decoder for receiving an N-bit digital input signal and converting the same into a first (N−1)-bit digital signal and a second (N−1)-bit digital signal; M (=2 N−1 ) current cells for supplying the current a current cell driver including a first switch group responsive to the first (N−1)-bit digital signal and a second switch group responsive to the second (N−1)-bit digital signal, and generating a first analog voltage corresponding to the first (N−1)-bit digital signals, wherein the first switch group includes a plurality of switches coupled to the M current cells and the second switch group includes a plurality of switches coupled to the M current cells; and an amplifying circuit for sampling and holding the first analog voltage and the second analog voltage with reference to a first clock signal and a second clock signal to generate a glitch-removed signal.
