Description
We present LIGHT01 (LGAD-based Integrated Granular Hybrid Timing ASIC), the first prototype in a new family of dedicated readout chips for Low Gain Avalanche Detector (LGAD) pixels. LIGHT01 implements an $8 \times 8$ pixel matrix with fully independent channels, each comprising a preamplifier optimized for LGAD capacitances, a fast discriminator, and a time-to-digital converter (TDC), with a target per-channel time resolution of 30ps. Designed in TSMC 28nm technology, the ASIC has undergone detailed post-layout simulations, demonstrating initial performance in terms of noise, jitter, and power consumption. First silicon is expected from fabrication in early 2026, with a complete test bench already prepared for rapid characterization. We also discuss the hybrid integration strategy with LGAD sensors and the roadmap for future iterations, aiming toward scalable, low-power, and radiation-tolerant architectures suitable for large-area timing systems, with potential application in future upgrades of the CMS detector and other collider experiments.
