模拟集成电路设计人员在设计推理中经常使用封闭形式的设计方程。然而,大多数时候,他们必须手工推导所有的方程。当对高阶效应感兴趣时,手动推导将变得更加困难。虽然符号电路分析的艺术已经取得了稳步的进展,但符号生成高阶效应的闭型方程仍然是一个研究较少的课题。本文提出了一种新的符号计算方法来生成差分细胞的二阶特征。它是一种利用微分单元结构对称性的微扰方法,并将其表述为由若干中间步骤组成的系统计算过程,每一步的计算都给出了一个紧凑的偏表达式。举例说明,应用符号摄动程序可以生成两个经典运算放大器的极零形式(以前未知)的闭合共模抑制比方程。
Analog integrated circuit designers always use closed-form design equations in design reasoning. However, most of the time, they have to derive all equations by hand. When high-order effects are of interest, manual derivation would become much harder. Although the art of symbolic circuit analysis has been making steady progress, symbolically generating closed-form equations for high-order effect is still a less well-studied subject. This paper proposes a novel symbolic computation method for generating the second-order characterization of differential cells. It is a perturbation approach that takes the advantage of structural symmetry in differential cells, and is formulated as a systematic computation procedure comprised of several intermediate steps, the computation of each step gives a compact partial expression. Examples are provided to illustrate that closed-form common-mode rejection ratio equations in pole-zero form (unknown before) for two classical operational amplifiers can be generated by applying the symbolic perturbation procedure.
