Abstract :
A charge-removal-replacement (CRR) technique is proposed to realize a low-voltage low-power current-steering digital-to-analog converter (DAC) for minimizing transition time in current switching. Implemented in a 0.18-mum CMOS process, the 10-bit 120-MS/s DAC focused on WLAN applications consumes only 2.5 mW from a single 1-V supply. The simulated monotonic performances achieve a mean value of |INL| < 0.14 LSB and |DNL| < 0.18 LSB, respectively. The averaged SFDR obtains 67.23/62.45 dB with/without the CRR technique
