工作点驱动的电路优化设计以电路直流工作点上一组独立的器件电压、电流作为优化变量。实现这一方法需要根据器件的工作点电压、电流确定器件尺寸。提出了用T-S模糊逻辑建立器件尺寸与工作点之间关系模型的方法，由此可准确、高效地完成直流工作点的设计，并开展进一步的优化。采用这一模型，以一个两级运算放大器为例，给出了工作点驱动优化设计的结果。

Operating-point driven design of analog circuits uses a group of independent device voltages and currents as the design variables.Its implementation need to convert the terminal voltages and currents into the size of the device.A method to realize such a conversion based on T-S fuzzy logic modeling is proposed in this paper.Accurate DC operating-point design is achieved and further circuit optimization can be carried out with this method.A design example of a two-stage operational amplifier is given to demonstrate the effectiveness of the method.
