“…The previously mentioned drawback of the law, the fact that the energy consumed will have a much higher price, because it will also contain several taxes, including the costs of energy transportation in the grid, can be addressed through the creation of energy communities. In several EU countries, the households located within a certain distance from a prosumer (500m in Spain) can consume the locally produced energy without paying the transportation costs [8]. This is the main reason people are motivated to legally create energy communities, and a similar regulation in our country could stimulate the association of citizens for energy and environmental benefits.…”

In 2019 the EU updated its energy policy (by adopting the Clean energy for all Europeans package) to enhance the transition from fossil fuels towards green energy - implementing the commitments of the EU’s Paris Agreement (adopted at the COP21 in December 2015) for reducing greenhouse gas emissions. The agreement on this new energy rulebook marked a significant step towards implementing the energy union strategy, published in 2015. Through this package, the EU has introduced the concept of energy communities in its legislation, notably as citizen energy communities and renewable energy communities. To incorporate the new regulations introduced by this package in the Romanian law, the Romanian government issued an Emergency Ordinance (143/December 28, 2021), that updates the Electrical energy and natural gas law (123/2012). The concept of energy communities is, from now on, part of our own legislation, and the creation of such communities in Romania can start, although there are still many questions regarding the effective steps to be taken in this process. This paper tries to emphasize the foreseen advantages of this new concept and how it could be implemented in our country.

“…A 3D physical model was utilized to optimize the number of copper winding turns for a planar power inductor in [18]. The authors in [19] presented an analysis and optimization tool for spiral planar inductors operated at high frequency, with the capability of determining the inductance and electrical parameters for different planar inductor geometries (e.g., octagonal and hexagonal). An electrical circuit model for a graphene-based on-chip power inductor was introduced in [20].…”

The on-chip integration of a power inductor together with other power converter components of small sizes and high-saturation currents, while maintaining a desired or high inductance value, is here pursued. The use of soft magnetic cores increases inductance density but results in a reduced saturation current. This article presents a 3D physical model and a magnetic circuit model for an integrated on-chip power inductor (OPI) to double the saturation current using permanent magnet (PM) material. A ~50 nH, 7.5 A spiral permanent magnet on-chip power inductor (PMOI) is here designed, and a 3D physical model is then developed and simulated using the ANSYS®/Maxwell® software package (version 2017.1). The 3D physical model simulation results agree with the presented magnetic circuit model, and show that in the example PMOI design, the addition of the PM increases the saturation current of the OPI from 4 A to 7.5 A, while the size and inductance value remain unchanged.

“…For millimeter wave phased array systems, in order to meet the system requirements of multi-band operation and multiapplication integration, wide operating bandwidth is becoming increasingly important [1][2][3] . As the first active gain stage closest to the transceiver antenna, the LNA needs to have sufficient power gain and a low noise figure to compensate for the noise figure of the front and rear modules and improve the sensitivity of the receiving system 4 . Therefore, due to the increasing bandwidth requirements of multi-band receivers, ultra-wideband LNAs have become a research focus in recent years 5,6 .…”

In this paper, an ultra-wideband Ka-band low-noise amplifier (LNA) is presented using broadband transformer matching and gate-drain feedback technology. The proposed LNA achieves ultra-wideband while maintaining the high integration and low power consumption of traditional source-degenerated LNAs. Additionally, cascading technology is used to increase the peak gain. The proposed LNA is implemented in a 55 nm CMOS process. The simulation results show that the LNA achieves a stable gain response in the frequency band of 21.7-36.5 GHz, and the peak power gain is 20.8 dB. The minimum noise figure is 4.4 dB. The DC power consumption is 15 mW with a compact chip area of 0.33 mm² .
