Zhishuai ZhangPhD张智帅博士

Zhishuai Zhang received his B.E. and Ph.D. degrees from Tsinghua University. His research focuses on analog/mixed-signal integrated circuit design—especially SAR ADCs and emerging amplifiers—as well as LLM-driven automation for mixed-signal IC design and agentic engineering for chip design.

He has held long-term visiting appointments at the University of Hong Kong and ETH Zürich, and has visited leading universities including the National University of Singapore, Waseda University, and the University of Tokyo. He has received international honors including the IEEE Solid-State Circuits Society Student Circuit Contest Award, the ISSCC Jack Kilby Outstanding Student Paper Award, and the ISSCC Student Travel Grant Award, as well as domestic funding and honors including support from the National Natural Science Foundation of China, the China Education Development Foundation Endeavor Scholarship, the MIIT–MOE Special Scholarship for High-Level IC Talent Development (Tier A), the Zhihua Integrated Circuit Scholarship, the Feng Chongxi Scholarship, and the Special Prize of the “Liu Runsheng Outstanding Teaching Assistant Award” from the Department of Electronic Engineering at Tsinghua University.

Research

Analog/Mixed-Signal Integrated Circuit Design

SAR ADCs, pipelined-SAR ADCs, emerging amplifiers, and related topics; architectural reconfiguration and multi-mode concurrency for programmable A/D converter arrays.

LLM-Driven Design Automation

Large-language-model–driven automation for mixed-signal IC design: from hierarchical compilation methods to structured reasoning for I/O schematic and layout generation.

Agentic Engineering for Chip Design

Connecting LLM agents to Cadence Virtuoso through open infrastructure such as Virtuoso-Bridge, turning repetitive manual work into automated workflows.
