Abstract:

This work presents a cryo-CMOS smart temperature sensor operating from room temperature down to 5 K. By adopting sensing elements (CMOS bulk diodes, pMOS/DTMOS in weak inversion) that circumvent the poor cryogenic performance of Si BJTs, a robust switched-capacitor second-order sigma–delta readout and cryogenic-aware design techniques, the sensor achieves …

Abstract:

Advanced packaging is becoming essential for designing hardware accelerators for large language models (LLMs). Different architectures, such as 2.5-D integration of memory with logic, have been proposed; however, the bandwidth limits the throughput of the complete system. Recent works have proposed memory on logic systems, where high bandwidth memory (HBM) …
