Nowadays most of the decisions in the field of energy supply lead to an increased use of renewable energy resources. Such decisions imply several consequences for instance in electrical power generation. Indeed, replacing conventional energy sources by mor ...
Among different analog-to-digital converter (ADC) architectures pipelined ADCs are the most suited for medium sampling frequencies (50-300MSPS) and medium resolutions, i.e. 8 to 14 bits. Having the lowest figure-of-merit (FOM) in its bandwidth and resoluti ...
Recently, there is a growing interest in developing so-called "smart" RFID tags for logistic applications. These smart tags incorporate sensing devices to monitor environmental parameters such as humidity and temperature throughout the supply chain. To ful ...
The electric power grid is undergoing significant changes and updates nowadays, especially on a production and transmission level. Initially, the move towards a distributed generation in contrast to the existing centralized one implies a significant integr ...
This paper proposes a new experimental investigation of the ageing mechanisms of super capacitors. Starting from the main ageing mechanisms of these devices reported in the literature, the paper proposes a suitably developed procedure aimed at evaluating t ...
The paper presents a set of experimental investigations related to the dynamic behavior of supercapacitors. The experimentally observed results are then used as inputs for the development of an improved version of one of the most common supercapacitor RC-e ...
