A Cryo-CMOS Smart Temperature Sensor for the Ultrawide Temperature Range From 5 K to 296 K

A Cryo-CMOS Smart Temperature Sensor for the Ultrawide Temperature Range From 5 K to 296 K 150 150
Author(s): D. Cerviño Fungueiriño, L. A. Enthoven, J. van Staveren, M. Babaie, F. Sebastiano

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 …

A Compact, Highly-Digital Sensor-Fusion-Based Joint V dd-Temperature Sensor for SoC Thermal Management

A Compact, Highly-Digital Sensor-Fusion-Based Joint V dd-Temperature Sensor for SoC Thermal Management 150 150
Author(s): Hikmet Seha Öztürk, Julian Arenas, Carlos Tokunaga, Nasser Kurd, Visvesh S. Sathe

Abstract:

This article presents a fine-grained thermal sensing network for thermal management in SoCs. Sensor nodes in this network are made up of joint supply voltage ( $V_{\mathrm {dd}}$ ) and temperature ( $T$ ) sensors, which are compact and highly digital. Measurements from these simple but imperfect sensors are jointly processed to extract …
