摘要

性能空间表示集成模拟电路的全部可实现性能，包括增益和带宽。基于最优和最不利值的知识，可以采用简化的仿真模型来优化系统设计过程。我们提出了一种完善的法向边界相交方法的改进变体，该方法用于在合理的时间内近似五维性能空间。基于这些近似，我们开发了一个实现系统级仿真的概念，用于设计用于模数转换器的可操作跨导放大器，以提高其采样率。为了证明我们的概念的可用性，我们进行了几个数值实验，并在并行坐标图中可视化数据，以便更好地用户理解。

Performance Space-Based ADC Development

Performance spaces represent the full range of attainable performances of an integrated analog circuit, including gain and bandwidth. Based on the knowledge of the optimal and least favorable values, simplified simulation models can be employed to optimize the system design process. We present a modified variant of the well-established Normal-Boundary Intersection method, which is used to approximate five-dimensional performance spaces in reasonable time. Based on these approximations, we develop a concept for implementing a system-level simulation that is used to design an operational transconductance amplifier for an analog-to-digital converter to improve its sampling rate. To demonstrate the usability of our concept, we perform several numerical experiments and visualize the data in parallel coordinates plots for better user comprehension.
