A fully integrated humidity sensor chip was designed, implemented, and tested. Utilizing the micro-stamping technology, the pseudo-3D sensor system-on-chip (SSoC) architecture can be implemented by stacking sensing materials directly on the top of a CMOS-fabricated chip. The fabricated sensor system-on-chip (2.28 mm × 2.48 mm) integrated a humidity sensor, an interface circuit, a digital contro...

Resumen. Sistemas basados en modulación de intensidad y detección directa tipo OOK (Conmutación de Encendido -Apagado, o del inglés OOK: On-Off Keying). Son de uso extendido en las redes fotónicas actuales debido a su sencillez y robustez pero no son los más eficientes en términos del uso del espectro. Sistemas de modulación de intensidad multi-simbólicos como M-PAM (del inglés: M-ary Pulse Amp...

The papers in this special section focuses on communications for mmany core processors and accelerators. Communications various forms have become increasingly important with the advent of diverse computing platforms, such as many-core CPUs, GPUs, FPGAs, machine learning accelerators, other domain-specific processors. Meanwhile, data-intensive workloads pose greater challenges to both on-chip of...

In the paper, a small antenna for 2.4 GHz body-centric wireless communications is proposed. With the folded ground and U-shaped slot, the antenna has an improved efficiency of 56.5% when it is very close to human body. In addition, the antenna has attractive radiation patterns for body-centric wireless communications.

In multicarrier data transmission using filter banks, adaptive equalizers can be introduced in the receiver in every sub-channel, to achieve high bit rates. Following conventional data transmission techniques, two approaches can be envisaged, namely the double sampling equalizer (DSE) and the critical sampling equalizer (CSE). Both schemes are discussed and assessed in the present paper, in the...
