在集成电路设计中,产品能否达到预定的设计参数,不仅取决于电路原理图的设计,还与版图设计有着密切关系。特别是模拟电路的设计对其版图设计中MOS的匹配度要求比较高,因为它直接影响到芯片是否能达到所要求的工作性能和指标的重要因素。本文主要针对设计中的MOS、电阻和电容等如何做到匹配进行分析和总结。 In integrated circuit design, the product can reach the predetermined design parameters, not only depends on the circuit schematic design, layout design also has a close relationship. In particular, the design of analog circuits requires a high degree of matching of the MOS in its layout design as it directly affects whether or not the chip can achieve the desired performance and performance. This article mainly for the design of the MOS, resistors and capacitors, etc. How to do the analysis and summary.
