近日,中科院微电子所微波器件与集成电路研究室(四室)超高速数模混合电路研发团队在超高速模数/数模转换器(ADC/DAC)、直接数字频率合成器(DDS)相关芯片研制上取得重要进展,成功研制出多款高性能芯片。研制成功的芯片包括:4GS/s8位ADC,该芯片由两路ADC交织而成,每路集成宽带采样保持电路并采用优化的折叠内插结构实现。芯片内部集成SPI编程接口,可以有效校准两
Recently, the CAS R & D team of the Microwave Devices and Integrated Circuits Research Laboratory (4-Room) of the Institute of Microelectronics of the Chinese Academy of Sciences in the ultra-high speed analog / digital converter (ADC / DAC) and direct digital frequency synthesizer Chip development made important progress, successfully developed a variety of high-performance chips. Developed chips include: 4GS / s8-bit ADC, the chip by the two ADC interwoven, each integrated broadband sample and hold circuit and the use of optimized folding interpolation structure to achieve. Integrated chip SPI programming interface, you can effectively calibrate the two
