Linear and Nonlinear Energy Harvesting in Concurrent Cellular and D2D Communication

Engineering Reports, Volume 7, Issue 9, September 2025.
In this study, an interference‐aided dual‐hop cooperative communication scenario is considered, where both cellular and energy‐constrained device‐to‐device (D2D) users coexist and share the same radio resources. The performance of the proposed model is studied considering both linear and nonlinear EH models employing time‐switching and power‐splitting ...

Bias‐Independent True Random Number Generator Circuit using Memristor Noise Signals as Entropy Source

Advanced Intelligent Systems, Volume 7, Issue 6, June 2025.
Random telegraph noise (RTN) characteristics of memristor depend on external environmental conditions. To avoid these bias‐dependent characteristics, a true random number generator circuit using the RTN current fluctuations of memristor is presented with an edge detection circuit and counter, and bias independence is experimentally demonstrated for ...
