CMOS technologies has always represented a key opportunity for smart and efficient mixed-signal systems design, covering several application fields (biomedical, physics and astrophysics experiments, sensors, telecommunication, Internet-of-Thing) having strong interest in fully-integrated solutions.
Integration of analog and digital circuits in the same die area is then sustained by the technological scaling-down, since lower power consumption can be achieved in mostly-digital systems due to the lower supply voltage.
The first interface of the mixed-signal systems with the external world is intrinsically analog. As a consequence, in order to achieve efficient and reliable circuits in deeply scaled and/or nm-range CMOS technologies, analog designers have to be able to manage the poor analog performance of the MOS transistors and at the same time to take advantage of the opportunities given by the increasing technological scaling-down. The scaling-down of the physical (length, size, etc.) and electrical (supply voltage) parameters leads to a significant improvement for digital circuits in terms of speed and power. This trend is not so automatic for analog circuits, since they experience severe drawbacks, like VDD/VTH decreasing (supply voltage and threshold voltage, respectively), higher sensitivity to Process-VoltageTemperature (PVT) variations, transistor intrinsic gain decreasing and in general higher power consumption.
Thanks to the increasing transition frequency of most recent CMOS technological process nodes, digital hardware is replacing several analog functions, representing an evident opportunity for high-data rate digital signal processing systems implementation. Digital designers must be able to operate in such stimulating scenario, where wide bandwidth digital signals have to be processed at higher speed and saving power.

Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Journal of Low Power Electronics and Applications is an international peer-reviewed open access quarterly journal published by MDPI.
