AI-designed radio chips look like QR codes and beat human ones

Princeton researcher Kaushik Sengupta has developed an AI that designs radio-frequency chips from scratch without human templates, producing unconventional layouts resembling QR codes that outperform human-designed chips. The work, published in IEEE Spectrum, challenges the traditional hand-crafted approach to RFIC design.

Radio-frequency chips — the parts in every phone, car radar, and satellite link that send and receive signals — have stayed a hand-crafted "dark art," mastered over years, even as CPUs and GPUs got designed by algorithm. Writing in IEEE Spectrum, Princeton's Kaushik Sengupta describes teaching AI to design these RFICs from scratch, with no human templates — and the results look nothing like human work. — Read the rest
