| Abstract: | Based on TSMC 0.18 μm CMOS technology,a 12-bit 500 MS/s D/A converter with 3.3 V analog supply voltage and 1.8 V digital supply voltage was designed using segmented current-steering structure.Simulation results showed that when sampling at 500 MS/s,the SFDR at 70 MHz and 240 MHz input was 89.9 dBc and 77.6 dBc respectively. |
