AI Analysis

This work addresses analog circuit design challenges for engineers, offering incremental improvements through AI integration.

The paper tackles analog circuit design by integrating AI techniques for device-level tuning and system-level co-optimization, resulting in improved performance and reduced design effort, as demonstrated on a transconductor and a keyword spotting application.

Artificial intelligence (AI) techniques are transforming analog circuit design by automating device-level tuning and enabling system-level co-optimization. This paper integrates two approaches: (1) AI-assisted transistor sizing using Multi-Objective Bayesian Optimization (MOBO) for direct circuit parameter optimization, demonstrated on a linearly tunable transconductor; and (2) AI-integrated circuit transfer function modeling for system-level optimization in a keyword spotting (KWS) application, demonstrated by optimizing an analog bandpass filter within a machine learning training loop. The combined insights highlight how AI can improve analog performance, reduce design iteration effort, and jointly optimize analog components and application-level metrics.
