“…One of the better available frequency sources, the AM0805, has an RC jitter of 500 ppm. While some research RC oscillators show promise towards tens of ppm [7], realizing the necessary stability with commercially available components requires the use of the higher-power crystal mode to maintain code coherence.

“…Fundamentally, a Slocalization tag requires very little: a stable clock source, a shift register, and a variable impedance antenna element. Leveraging recent advances in near threshold circuit and oscillator designs, these components could be realized with a power budget on the order of nanowatts [7]. As nodes shrink, however, their physical antennas necessarily shrink as well, significantly reducing gain.…”

Ultra wideband technology has shown great promise for providing high-quality location estimation, even in complex indoor multipath environments, but existing ultra wideband systems require tens to hundreds of milliwatts during operation. Backscatter communication has demonstrated the viability of astonishingly low-power tags, but has thus far been restricted to narrowband systems with low localization resolution. The challenge to combining these complimentary technologies is that they share a compounding limitation, constrained transmit power. Regulations limit ultra wideband transmissions to just -41.3 dBm/MHz, and a backscatter device can only reflect the power it receives. The solution is long-term integration of this limited power, lifting the initially imperceptible signal out of the noise. This integration only works while the target is stationary. However, stationary describes the vast majority of objects, especially lost ones. With this insight, we design Slocalization, a sub-microwatt, decimeter-accurate localization system that opens a new tradeoff space in localization systems and realizes an energy, size, and cost point that invites the localization of every thing. To evaluate this concept, we implement an energy-harvesting Slocalization tag and find that Slocalization can recover ultra wideband backscatter in under fifteen minutes across thirty meters of space and localize tags with a mean 3D Euclidean error of only 30 cm.

Abstract-The search goes on for another ground breaking phenomenon to reduce the ever-increasing disparity between the CPU performance and storage. There are encouraging breakthroughs in enhancing CPU performance through fabrication technologies and changes in chip designs but not as much luck has been struck with regards to the computer storage resulting in material negative system performance. A lot of research effort has been put on finding techniques that can improve the energy efficiency of cache architectures. This work is a survey of energy saving techniques which are grouped on whether they save the dynamic energy, leakage energy or both. Needless to mention, the aim of this work is to compile a quick reference guide of energy saving techniques from 2013 to 2016 for engineers, researchers and students.

In this article, a ring oscillator with Temperature Compensation Effect is proposed in 0.18 μm CMOS. The ring oscillator is composed of 31 stages of inverters in series. The change in ambient temperature will cause the oscillator frequency to deviate. Therefore, this research uses a voltage circuit with a positive temperature coefficient as the power supply for the oscillator circuit, so that the ring oscillator can output stable oscillation center frequency regardless of ambient temperature. The ring oscillator has been verified by simulation and experimental testing. The ambient temperature is within the range of −40°C to 80°C. The output frequency of the ring oscillator is stable at 33 kHz ± 0.50 kHz. The frequency error is within 1.6%. Temperature stability was 120 ppm/°C. At 1 MHz off the carrier, the phase noise is as low as −151.2 dBc/Hz and the total power dissipation is 210 μW. Compared with the previous scheme, the chip area and power consumption are lower. This circuit module can provide a clock signal for the timer when the UWB chip sleeps.
