A compact direct digital frequency synthesizer (DDFS) for system-on-chip implementation of the high precision rubidium atomic frequency standard is developed. For small chip size and low power consumption, the phase...
This paper presents a 2GS/s 10bit CMOS digital-to-analog converter (DAC) that consists of two unit current-cell matrixes for 6MSBs and 4LSBs, respectively, trading off between the precision and size of the chip. Cur...
