摘　　要：OrCAD PSPICE是一个在PC机上应用比较广泛的电路模拟工具。在模拟IC设计时为了考虑体偏效应,需要具有栅G、源S、漏D、体B四个端口的器件,但PSPICE并不提供该器件的图形化输入,而且对于不同的生产工艺其SPICE模型也不相同。本文建立了适用于特定工艺的用于图形化输入方式的四端口MOSFET模型。模拟结果表明所建模型具有正确的器件特性,而且在IC中模拟的结果也是正确的,适用在PC机上应用OrCAD PSPICE软件进行含四端口MOSFET的电路的图形化输入工作。OrCAD PSPICE is a widely used program for circuit simulation on personal computers.4-terminal MOS devices are necessary for analogue integrated circuit design, because usually thebody bias effect cannot be neglected. But PSPICE does not support the method to graphically inputsuch devices, and a SPICE model varies from foundry to foundry. In this paper, the MOSFET modelssuitable for graphical interface are created for a certain technology. The simulation results show thatnot only the characteristics of the created MOSFET device but also the circuits’ function withthese devices are correct. So it is possible to input circuit schematics with 4-terminal devices graphi-cally in OrCAD PSPICE.
