三、CAD在模拟集成电路分析与设计中的应用自1978年初以来,我们陆续对我厂生产的十四种模拟集成电路进行了计算机辅助分析与设计,求出了各电路的直流工作点、失调电压、偏置电流、失调电流、输入阻抗、共模电压范围、功耗、幅频特性、相频特性曲线、转折频率分布情况、开环3分贝带宽、单位增益带宽、推荐相位补偿参数、共模抑制比曲线等.获得的大量资料对集成电路的设计、测试、应用等工作都起了很好的作用. Third, the CAD in the analog integrated circuit analysis and design applications Since the beginning of 1978, we have one after another on the plant I produced fourteen kinds of analog integrated circuits for computer-aided analysis and design, obtained the circuit DC operating point, offset Voltage, Bias Current, Offset Current, Input Impedance, Common Mode Voltage Range, Power Dissipation, Amplitude-Frequency Characteristics, Phase-Frequency Characteristic Curves, Corner Frequency Distribution, Open Loop 3 dB Bandwidth, Unity Gain Bandwidth, Recommended Phase Compensation Parameters, Total Mode suppression ratio curve, etc. The large amount of data obtained has played a very good role in the design, testing, application and other work of integrated circuits.
