Abstract

In this paper, we present a technique for estimating the gain, bandwidth, power and area of analog integrated circuits. A two-step approach is adopted to speed up the estimation process and handle larger analog systems. In the first step, the performance of basic analog components is estimated using a knowledge-based approach. Then, component models are generated with the estimates produced at this phase. In the second phase, we use a symbolic analysis methodology to evaluate the performance at the system level. The system net-list is represented by a signal flow graph (SFG) using the component models generated at the previous phase. The SFG approach allows one to handle feedback loops at the system level.
带反馈的模拟集成电路高电平合成的二电平性能估计
本文提出了一种估算模拟集成电路增益、带宽、功率和面积的方法。采用两步法来加快估计过程和处理更大的模拟系统。在第一步,使用基于知识的方法估计基本模拟元件的性能。然后,使用在此阶段产生的估计生成组件模型。在第二阶段,我们使用符号分析方法来评估系统级的性能。系统网络列表由信号流图(SFG)表示,该信号流图使用在前一阶段生成的组件模型。SFG方法允许在系统级别处理反馈循环。
