Special Issue Information

Dear Colleagues,

The Internet of Things (IoT) is the next wave of immense innovation for electronics, which is promising to change the whole world. At the heart of this diverse ecosystem are the various sensor nodes, including chemical, physical, electrical, optical, and acoustic devices. By reducing power consumption, these devices will be able to last much longer on their batteries, and require little to no maintenance. The drive to develop ultra-low power sensors will increasingly push the boundaries of IoT to new application areas.

This Special Issue invites innovative contributions in the quickly growing field of low power sensors for IoT. The sensing platforms to be considered cover a wide range of devices: imaging, optical, or acoustic. Low power techniques for sensor data collection, processing as well as wireless communications will be the focus of this issue.  Contributions may include, but are not limited to, device, circuit and system level techniques, simulation, and modeling techniques.

This paper presents hardware-efficient Delta Sigma linear processing circuits for the next generation low-power VLSI devices in the Internet-of-things (IoT).We first propose the P-N (positive-negative) pair method to manipulate both the analog value and length of a first-order Delta Sigma bit sequence. We then present a binary counter method. Based on these methods, we develop Delta Sigma domain on-the-fly digital signal-processing circuits: the Delta Sigma sum adder, average adder and coefficient multiplier. The counter-based average adder can work with both first-order and higher-order Delta Sigma modulators and can also be used as a coefficient multiplier. The functionalities of the proposed circuits are verified by MATLAB simulation and FPGA implementation. We also compare the area and power between the proposed Delta Sigma adders and a conventional multi-bit adder by synthesizing both circuits in the IBM 0.18-μm technology. Synthesis results show that the proposed Delta Sigma processing circuits can extensively reduce circuit area and power. With 100 inputs, a Delta Sigma average adder saves 94% of the silicon area and 96% of the power compared to a multi-bit binary adder. The proposed circuits have the potential to be widely used in future IoT circuits. Full article
