This work presents a 2.4 GHz low noise amplifier (LNA) for wireless sensor network in CMOS 0.13-μm Silterra process. The forward body bias technique with cascode configuration has been adopted in order to implement a suitable LNA for low power consumption target. The supply voltage was varied from 0.4 V to 0.6 V as to optimize the tradeoffs for LNA performances. The simulation results show that...

In this article, a distributed-swing-boosting and harmonic-impedance-expanding multi-core oscillator is proposed to achieve low phase noise high figure-of-merit (FoM), simultaneously. First, distributed-coupling topology introduced reduce the chip area with no mode ambiguity. Then, structure developed boost gate swing square-like waveform of $V_{\text...

This paper introduces a new high-performance successive approximation register (SAR) analog-to-digital converter (ADC) designed for high-speed and low-power wireless local area network (WLAN) applications using SMIC 55 nm 1p8m CMOS process. The design employs several innovative techniques, including an improved bootstrap switch with high linearity, 4-reference voltage method to minimize capacit...

Metallic nanostructures are highly attractive for refractive index sensing, as the evanescent field from associated plasmonic resonances resides in close proximity to adjacent analyte media. However, this benefit is often reduced due broad lineshapes producing poor quality factors. The rational design provides strategies narrowing modes by incorporating photonic diffraction, which promotes surf...

Fano resonances in metamaterial are important due to their low-loss subradiant behavior that allows excitation of high quality ( Q ) factor extending from the microwave optical bands. have recently showed great potential areas modulation, filtering, and sensing for extremely narrow linewidths. However, a system arise interaction all form structure, limiting tunability resonances. Besides, trace...

The bolometric effect (BE) allows to electrically monitor spectral characteristics of plasmonic sensors, but trade-off between sensitivity, response time, and strong light absorption is an important challenge. Here, the BE for a high resistance sensitivity sensor proposed studied based on multilayer structure at 26 °C. By generating coupling incident wave surface plasmon polaritons (SPPs), very...
