Special Issue Information

Dear Colleagues,

The Internet of Things is expected to be the next-generation network connecting people to people (P2P), people to machine (P2M), and machine to machine (M2M), and will be the “network of the networks” that incorporates a diversity of functionalities and technologies in support of new applications and services in a “smart” world.

Energy efficiency and miniaturization are the two most critical technical challenges for the hardware implementation of microelectronic systems enabling Internet of Things. Low-power smart systems on a chip are the key enabling solutions.

This Special Issue is aimed at presenting the latest advances and future challenges in low-power system-on-chip designs and implementations for communication, sensing, processing, actuation, energy harvesting and management, enabling Internet of Things.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. 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.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 1800 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

This work proposes a novel demodulation circuit to address the implementation of Wake-Up Receivers (Wu-Rx) in Wireless Sensor Nodes (WSN). This RF demodulator, namely Modulated Oscillator for envelOpe Detection (MOOD), is compatible with both FSK and OOK/ASK modulation schemes. The system embeds an LC oscillator, an envelope detector and a base-band amplifier. To optimize the trade-off between RF performances and power consumption, the cross-coupled based oscillator is biased in moderate inversion region. The proof of concept is implemented in a 65 nm CMOS technology and is intended for the 2.4 GHz ISM band. With a supply voltage of 0.5 V, the demodulator consumes 120 μW and demonstrates the demodulation of OOK and FSK at a data rate of 500 kbps. Full article

In this work, a Radio Frequency (RF) Energy Harvester comprised of a differential Radio Frequency-to-Direct Current (RF-DC) converter realized in ST130 nm Complementary Metal-Oxide-Semiconductor (CMOS) technology and a customized broadband Printed Circuit Board (PCB) antenna with inductive coupling feeding is presented. Experimental results show that the system can work with different carrier frequencies and thanks to its reconfigurable architecture the proposed converter is able to provide a regulated output voltage of 2 V over a 14 dB of RF input power range. The conversion efficiency of the whole system peaks at 18% under normal outdoor working conditions. Full article

This paper proposes a review of several circuits for communication and wireless sensing applications implemented on cellulose-based materials. These circuits have been developed during the last years exploiting the adhesive copper laminate method. Such a technique relies on a copper adhesive tape that is shaped by a photo-lithographic process and then transferred to the hosting substrate (i.e., paper) by means of a sacrificial layer. The presented circuits span from UHF oscillators to a mixer working at 24 GHz and constitute an almost complete set of building blocks that can be applied to a huge variety communication apparatuses. Each circuit is validated experimentally showing performance comparable with the state-of-the-art. This paper demonstrates that circuits on cellulose are capable of operating at record frequencies and that ultra- low cost, green i.e., recyclable and biodegradable) materials can be a viable solution to realize high frequency hardware for the upcoming Internet of Things (IoT) era.
