A 1 V 6-bit 2.4 GS/s Nyquist CMOS DAC for UWB systems
A 6-bit 2.4 GS/s current-steering DAC fabricated in a 65 nm CMOS technology for ultra-wideband (UWB) systems is presented. The prototype achieves a measured spurious-free dynamic range (SFDR) of more than 36 dB over the Nyquist bandwidth at 2.4 GS/s. Among the 50 measured samples, DNL/INL of 0.02/0....

Summary: | A 6-bit 2.4 GS/s current-steering DAC fabricated in a 65 nm CMOS technology for ultra-wideband (UWB) systems is presented. The prototype achieves a measured spurious-free dynamic range (SFDR) of more than 36 dB over the Nyquist bandwidth at 2.4 GS/s. Among the 50 measured samples, DNL/INL of 0.02/0.02 LSB was the lowest achievable value. The DAC core occupies an area of merely 0.023 mm 2 through simplified circuit and careful layout. To operate from a relatively low analog power supply of 1 V, a portion of current cell is implemented using low threshold voltage devices. Total maximum power consumption, including the low voltage differential signaling (LVDS) stage, is 14 mW at 2.4 GS/s. |
