        利用自主知识产权的DACIP核设计和电路高速工作的设计技术,研发出硅(Si)基CMOS方式2GHz合成时钟频率的ROM-Less直接数字频率合成芯片。又从原理分析到芯片设计及流片验证完整地研发出融入过采样Σ/Δ技术的新型高分辨率直接数字频率合成芯片。上述工作受到国际同行的重视与好评。

        With the designing technology of the self-owned intellectual property right-DAC IP core andhigh-speed circuit, the Neural Network & High Speed Circuit Lab, Institute of Semiconductors, has developed a 2GHz CMOS ROM-Less Direct Digital Frequency Synthesizer (DDS) chip, and meanwhile, the Lab has completed a full range of research on the new type of high resolution DDS chip involving over-sampling Σ/Δ technology. The above work has attracted attention and won high appraisal from IEEE ISCAS 2005 and IEEE VLSI 2005.
