IMPLEMENTATION OF CONFIGURABLE RING OSCILLATOR PUF WITH SYMMETRICAL PATHS ON FPGA

open access: yesБезопасность информационных технологий
This paper proposes a novel Physical Unclonable Function (PUF) scheme based on a configurable ring oscillator. The circuit utilizes the measurement of signal propagation delay differences along symmetric paths constructed using the internal resources of ...

A 24-GHz, +14.5-dBm fully integrated power amplifier in 0.18-μm CMOS [PDF]

open access: yes, 2005
A 24-GHz +14.5-dBm fully integrated power amplifier with on-chip 50-[ohm] input and output matching is demonstrated in 0.18-μm CMOS. The use of substrate-shielded coplanar waveguide structures for matching networks results in low passive loss and small ...

The newfound relationship between extrachromosomal DNAs and excised signal circles

open access: yesFEBS Letters, EarlyView.
Extrachromosomal DNAs (ecDNAs) contribute to the progression of many human cancers. In addition, circular DNA by‐products of V(D)J recombination, excised signal circles (ESCs), have roles in cancer progression but have largely been overlooked. In this Review, we explore the roles of ecDNAs and ESCs in cancer development, and highlight why these ...

Statistical Power Supply Dynamic Noise Prediction in Hierarchical Power Grid and Package Networks [PDF]

open access: yes, 2008
One of the most crucial high performance systems-on-chip design challenge is to front their power supply noise sufferance due to high frequencies, huge number of functional blocks and technology scaling down.

Conserved structural motifs in PAS, LOV, and CRY proteins regulate circadian rhythms and are therapeutic targets

open access: yesFEBS Letters, EarlyView.
Cryptochrome and PAS/LOV proteins play intricate roles in circadian clocks where they act as both sensors and mediators of protein–protein interactions. Their ubiquitous presence in signaling networks has positioned them as targets for small‐molecule therapeutics. This review provides a structural introduction to these protein families.

A 77-GHz Six-Port Sensor for Accurate Near-Field Displacement and Doppler Measurements

open access: yesSensors, 2018
A continuous-wave (CW) radar sensor design based on a millimetre-wave six-port interferometer is proposed. A complete sensor prototype is conceived of, fabricated and measured at 77 GHz for short-range professional and industrial applications.

The (Glg)ABCs of cyanobacteria: modelling of glycogen synthesis and functional divergence of glycogen synthases in Synechocystis sp. PCC 6803

open access: yesFEBS Letters, EarlyView.
We reconstituted Synechocystis glycogen synthesis in vitro from purified enzymes and showed that two GlgA isoenzymes produce glycogen with different architectures: GlgA1 yields denser, highly branched glycogen, whereas GlgA2 synthesizes longer, less‐branched chains.

An Investigation of Process Variations and Mismatch Characteristics of Vertical Bipolar Junction Transistors

open access: yesIEEE Access, 2023
Bipolar junction transistors (BJT) are widely used integrated devices for analog circuits. For most of analog applications, the process variation and the match performance of BJT pairs are critical for the circuit design.
