摘要:
介绍了典型N-数字小数分频器的工作过程,在此基础上分析了由级联累加器实现的积分功能.其累加器溢出按Psscal三角形数值计算.利用计算结果可实现频率合成器的相位补偿及减小相位抖动.最后给出了4级Psscal三角形数值计算的实现电路图及模拟结果,分析了该电路的一些特点.该电路已嵌入在已设计的Σ-Δ调制小数分频专用集成电路中,采用无锡上华0.6 μmCMOS双铝双多晶标准单元工艺制造,并在微波信号源仪器上应用.
Abstract:
The working process of typical N-Digital fractional frequency divider is introduced and the integration function performed by cascaded accumulators is analyzed. The overflow of the accumulators is calculated according to a Pascal triangle. Phrase compensation and reduction of phrase vibration of the frequency synthesizer can be accomplished using the calculation results. At last, a 4-level Pascal triangle circuit is presented and simulated, and the characteristics of the circuit is also introduced. The circuit has been embedded in the ASIC of ∑-Δ fractional frequency divider which is based on 0.6 μm micron double poly-silicon and double metal CMOS technology in Wuxi CSMC-HJ Co.Ltd., and it has been applied on the microwave signal generator.
