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 …

A 200 GHz Wideband and Low-Power Direct-Downconversion Receiver Element in 16nm FinFET Technology

A 200 GHz Wideband and Low-Power Direct-Downconversion Receiver Element in 16nm FinFET Technology 150 150
Author(s): Ethan Chou, Hesham Beshary, Nima Baniasadi, Ali Niknejad

Abstract:

This paper presents a wideband and low-power direct-downconversion 200 GHz receiver element for digital-beamforming applications implemented in 16nm FinFET technology. Wideband and low integrated receiver noise figure of 9.8 dB across a 21 GHz baseband bandwidth is realized with a differential low-noise amplifier leveraging an active input balun stage, while wideband gain of 29 …

An 8-Bit 400-MS/s 1-Then-2-Bit/Cycle SAR ADC With Comparator Rotation-Based Input-Independent Background Offset Calibration

An 8-Bit 400-MS/s 1-Then-2-Bit/Cycle SAR ADC With Comparator Rotation-Based Input-Independent Background Offset Calibration 150 150
Author(s): Changjoo Kim, Sooho Park, Yohan Choi, Minkyun Shim, Woojin Lee, Donghwi Seo, Chulwoo Kim

Abstract:

This letter presents an 8-bit 400 MS/s 1-then-2-bit/cycle successive approximation register (SAR) analog-to-digital converter (ADC) employing a comparator rotation-based background offset calibration (CRBC) technique. Unlike conventional 1-then-2-bit/cycle architectures, where calibration validity depends on the input voltage, the proposed comparator rotation-based background calibration enables input-independent background calibration, …
