Hands-on design, or direct co-design, of analog front-end blocks (TIA, CTLE, VGA, sampler, TX driver, clocking) in a high-speed SerDes or optical transceiver, with a deep understanding of how their bandwidth, noise, linearity, offset, and jitter shape the link, reasoned from a schematic and a Spectre result rather than a behavioral model. Backed by industry giants like NVIDIA, AMD, Mediatek, and Intel and manufactured in partnership with the world's leading semiconductor ecosystem, Ayar Labs' co-packaged optics solution is key to unleashing next-generation AI scale-up architectures.
