Graphene microwave transistors on sapphire substrates

, 2011
We have developed metal-oxide graphene field-effect transistors (MOGFETs) on sapphire substrates working at microwave frequencies. For monolayers, we obtain a transit frequency up to ~ 80 GHz for a gate length of 200 nm, and a power gain maximum ...

Power amplifier/low noise amplifier RF switch

Electronics Letters, 2000
Front-end RF switches commonly use PIN diodes as the switching element. A novel RF switch using the existing front-end power amplifier and low noise amplifier to give better performance with reduced component count and lower cost is demonstrated.

From Clinic to Computation: Multiscale Bioengineering Strategies for Durable Biological Aortic Valve Replacements

Advanced Functional Materials, EarlyView.
Bioprosthetic aortic valves have revolutionized the treatment of aortic stenosis, but their durability is limited by structural valve deterioration (SVD). This review focuses on the pericardial tissue at the heart of these valves, examining how its mechanical properties and calcification drive fatigue and failure.

A 120 GHz Hybrid Low Noise Amplifier in 40 nm CMOS

IEEE Access
In this paper, we present a 6-stage 120 GHz hybrid low noise amplifier (LNA) for sub-THz radar systems. To enhance the noise figure (NF) and gain performance of the LNA, we propose a hybrid architecture that utilizes a combination of 2-stage single-ended

Artifact‐Minimizing Ultrathin Transparent Electrodes Fabricated via iCVD for In Vivo Optogenetic Stimulation and Neural Signal Monitoring of Primary Visual Cortex

Advanced Functional Materials, EarlyView.
We present ultrathin flexible transparent electrodes through iCVD‐enabled molecular control of 10 nm gold films on poly(dimethylaminomethylstyrene). In vivo validation demonstrated photoelectric artifact reduction vs. opaque electrodes and preservation of natural neural dynamics.
