The agent designed a **240–251 GHz sub-THz transmitter** in a **90 nm SiGe BiCMOS process**, including a **60 GHz push-push Colpitts VCO**, power drivers, a frequency doubler, and a differential bowtie antenna. The final design achieved **+5.1 to +6.3 dBm** output power, **-80 to -88 dBc/Hz** phase noise at 1 MHz offset, and **361 mW** DC power consumption across an 11 GHz tuning range.\n\nThe paper describes a **semi-autonomous workflow** where the agent handles sub-block synthesis and matching networks while humans oversee parasitic extraction and EM verification. The authors frame this as a step toward **‘text-to-ASIC’** hardware design, though the work remains experimental and not yet deployed in industry tools.","keyPoints":["Claude Opus 4.8 LLM agent designed a **240–251 GHz sub-THz transmitter** using EDA tools like Cadence Virtuoso/Spectre and Ansys HFSS","Final design delivered **+5.1 to +6.3 dBm** output power and **-80 to -88 dBc/Hz** phase noise at 1 MHz offset","Researchers call it a **‘text-to-ASIC’** prototype, but it’s not yet a commercial product or tool"],"whyItMatters":"If scalable, AI-driven RF design could slash time and cost for high-frequency hardware, accelerating 5G/6G and mmWave innovation beyond manual EDA workflows.","category":{"slug":"robotics","name":"Robotics & Physical AI","url":"https://digestai.news/category/robotics"},"entities":{"companies":[],"models":["Claude Opus 4.8"],"people":[]},"firstPublishedAt":"2026-10-26T04:00:00Z","updatedAt":"2026-10-26T04:00:00Z","sourceCount":1,"hasPrimarySource":true,"sources":[{"outlet":"arXiv cs.AI","title":"TACS-RF: Tool-driven Agentic Circuit Synthesis of RF and mmWave Modules","url":"https://arxiv.org/abs/2610.31882","publishedAt":"2026-10-26T04:00:00Z","type":"primary","primary":true,"lead":true}],"sourceNotes":null,"discussions":[],"thread":null,"cite":{"text":"Digest AI, \"Researchers use Claude Opus 4.8 to auto-design sub-THz transmitter with EDA tools\", 26 October 2026, https://digestai.news/story/researchers-use-claude-opus-4-8-to-auto-design-sub-thz-transmitter-wit","publisher":"Digest AI","title":"Researchers use Claude Opus 4.8 to auto-design sub-THz transmitter with EDA tools","datePublished":"2026-10-26T04:00:00Z","url":"https://digestai.news/story/researchers-use-claude-opus-4-8-to-auto-design-sub-thz-transmitter-wit"},"generatedBy":"Written by Digest AI's editorial model from the linked sources; the sources are the record.","license":"Headlines, digests and key points are written by Digest AI and may be quoted with a link to the story page.
