5G is now and what’s next?
5G deployments have only recently started, and releases beyond R15 will continue to tap into the tremendous potential of 5G. However, as a new generation of cellular technology typically appears every 8-10 years, 6G can be expected around 2030.

To ensure the stability of voltage regulators and switchedmode power supplies, the control loop behavior must be measured and characterized. A well compensating voltage controller enables stable output voltages and reduces the influence of load changes and supply voltage variations. The quality of this control circuit...

This paper introduces a new DC/DC power supply architecture, called “Yeaman Topology”. The main characteristic of this topology is to separate the output voltage regulation function from the bulk power conversion function, implementing two stages that share a common input, and have their outputs in series....

The trend in recent years for information and communications devices to have high performance and down - sizing has resulted in higher - density devices. This has created a demand for cooling fans to achieve higher cooling performance (air flow - static pressure characteristics) without changing in size.
Here Sank...

Even though the eGaN FET was designed and optimized as a power-switching device, it also exhibits good RF characteristics. The smallest 200 V eGaN FET, EPC2012, was selected for RF evaluation and should be viewed as a starting point from which the RF characteristics of future eGaN FET part numbers can be optimized for...
