Abstract:

This article presents a Nyquist-rate Analog-to-digital converter (ADC) operating from 0.5 to 2.5 GS/s based on an open-loop resettable ring VCO (R-RVCO). By inherently embedding the $1 {\,}-{\,}z^{-1}$ transfer function, the R-RVCO eliminates the need for an explicit differentiator, suppresses VCO phase-noise (PN) integration, and avoids quantization-noise (QN) shaping within …

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 …
