2.4-GHz CMOS Power Amplifier With Common-Mode Self-Rejection Technique to Suppress Even Harmonics

IEEE Access
In this study, we propose a common-mode self-rejection (CMSR) technique to improve the linearity of CMOS differential power amplifiers. The proposed CMSR technique is implemented through a matching network consisting of a Guanella transformer between the

Simple Scheme for the Implementation of Low Voltage Fully Differential Amplifiers without Output Common-Mode Feedback Network

Journal of Low Power Electronics and Applications, 2020
A simple scheme to implement class AB low-voltage fully differential amplifiers that do not require an output common-mode feedback network (CMFN) is introduced. It has a rail to rail output signal swing and high rejection of common-mode input signals. It

Oxygen Supply of Islets of Langerhans by Photosynthetically Active Microalgae in Bioprinted Co‐Cultures Maintains Their Function in a Hypoxic Environment

Advanced Healthcare Materials, EarlyView.
This study developed a bioprinted co‐culture system embedding rat pancreatic islets and Scenedesmus sp. microalgae spatially defined in close vicinity. Red light was found optimal to ensure microalgal photosynthesis while maintaining islet viability and functionality. A tailored co‐culture medium supported both cell types.

Design of Broadband Aperture-Coupled Microstrip Antenna Arrays With Differential Feeding

IEEE Access
This paper proposes the design of broadband microstrip antennas fed by differential microstrip lines. The designed broadband antennas are composed of two capacitively coupled rectangular stacked patches excited through a dog-bone shaped aperture by short-

Common Mode Rejection Calculations on the Debuncher Upgrade [PDF]

, 2001
The 4-8 GHz Transverse Debuncher Cooling Systems are power limited. Misalignments and imperfections in the transverse pickup arrays will generate a longitudinal signal in addition to the betatron signal. This longitudinal signal can use up a significant fraction of the precious TWT power if the imperfections are large enough.

Mixed‐Metal Promotion in a Manganese‐Molybdenum Oxynitride as Catalyst to Integrate C─C and C─N Coupling Reactions for the Direct Synthesis of Acetonitrile from Syngas and Ammonia

Advanced Materials, EarlyView.
Transition metal oxy/carbo‐nitrides show great promise as catalysts for sustainable processes. A Mn‐Mo mixed‐metal oxynitride attains remarkable performance for the direct synthesis of acetonitrile, an important commodity chemical, via sequential C─N and C─C coupling from syngas (C1) and ammonia (N1) feedstocks.

Common Mode Rejection of Stack Tail Kicker Hybrids [PDF]

, 1985
The betatron heating of the core is commonly agreed to be due to a undesired difference mode in the kickers. This could be due to tolerances and mistakes in the kickers or in the hydrids which ideally drive the kickers in the sum mode. The purpose of this note is to estimate the effect of the latter.

From Fiber Architecture to Functional Attachment: A Clinically Relevant, Mechanically Tunable Cardiac Patch

Advanced Materials, EarlyView.
A personalizable platform featuring a multi‐zonal cardiac patch design at clinical scale enables precise customization of fiber architecture at micro‐ and macroscale via melt electrowriting. Distinct scaffold zones support cell alignment with mechanical force transfer and epicardial attachment.

A Tunable Balanced Coupler With Improved Phase Balance and Extended Bandwidth

IEEE Access, 2019
This paper proposes a balanced coupler with improved phase balance and extended bandwidth for a wide range of tunable power-dividing ratios. This differential coupler uses only two varactors and can demonstrate tunable power-dividing ratio and quadrature
