Abstract:

This article presents a high-accuracy, low-drift 16MHz RC frequency reference implemented in a standard 180 nm CMOS process. It consists of a frequency-locked loop (FLL), which locks the output frequency of a digitally controlled oscillator (DCO) to the time constant of a Wien Bridge (WB) filter. A PNP-based temperature sensor (TS) …

An Eye-Opening Arbiter PUF With Auto-Error Detection and PVT-Robust Masking Achieving a BER of 2e-8

An Eye-Opening Arbiter PUF With Auto-Error Detection and PVT-Robust Masking Achieving a BER of 2e-8 150 150
Author(s): Bjoern Driemeyer, Holger Mandry, David-Peter Wiens, John G. Kauffman, Joachim Becker, Maurits Ortmanns

Abstract:

A hybrid ring oscillator (RO)/ arbiter physical unclonable function (PUF) is implemented in a 28-nm CMOS, where two competing ROs accumulate a sufficiently large phase difference exceeding a predefined deadzone (DZ). The resulting eye-opening arbiter (EOA) architecture enables a prediction of PUF bit stability over temperature change (from −40 °C to $125~^{\…

A Sub-Threshold Oscillator-Based High-Accuracy Temperature Sensor With Tolerance to Supply Fluctuation and Device Aging

A Sub-Threshold Oscillator-Based High-Accuracy Temperature Sensor With Tolerance to Supply Fluctuation and Device Aging 150 150
Author(s): Wei Wang, Yumin Su, Shayok Dutta, Liwen Jiang, Zhiyu Chen, Zhanghao Yu, Caleb Kemere, Kaiyuan Yang

Abstract:

Accurate, low-power, and compact temperature sensors are demanded in a wide range of biomedical, environmental, and industrial sensing applications. This article presents an accurate and precise CMOS temperature sensor based on a sub-threshold ring oscillator (RO) in 180 nm. The sensing core employs a five-stage super cut-off contention-free (SCCF) delay cell …
