A High-Efficiency 28-GHz Outphasing PA with 23-dBm Output Power Using a Triaxial Balun Combiner

There is a growing demand for broadband-cellular traffic which is the catalyst toward 5G wireless standardization for the roll-out of gigabit-per-second mm-Wave technology in the next few years. Gigabit-per-second millimeter-wave (mm-wave) access and backhaul networks at 28GHz demand high-order QAM, OFDM, and/or carrier-aggregated waveforms that force the PA to operate under high peak-to-average power ratio (PAPR). High PAPR requirements aggravate the design of mm-wave Si CMOS and SiGe BiCMOS PAs since a linear response and high efficiency are simultaneously desired. Recent work has demonstrated mm-wave PAs with peak efficiency exceeding 30% at 28GHz for output powers above 20dBm. However, high average efficiency associated with high-PAPR waveforms remains elusive. To improve average efficiency, circuit techniques based on Doherty and outphasing have been demonstrated in mm-wave bands. Earlier work using these techniques showed average efficiency with QAM waveforms that is well under 20%.

Local Binary Pattern Network (LBPN)

Convolutional Neural Networks (CNN) have had a notable impact on many applications. Modern CNN architectures such as AlexNet, VGG, GoogLetNet, and ResNet have greatly advanced the use of deep learning techniques into a wide range of computer vision applications. These gains have surely benefited from the continuing advances in computing and storage capabilities of modern computing machines. Memory and computation efficient deep learning architectures are an active area of research in machine learning and computer architecture. Model size reduction and efficiency gains have been reported by selectively using binarization of operations in convolutional neural networks that approximate convolution by reducing floating point arithmetic operations.

Automated Immersion Mode Ice Spectroscopy

Ice nucleating particles (INPs) suspended in the Earth’s atmosphere influence cloud properties and can affect the overall precipitation efficiency and predictability of cloud systems worldwide. INPs induce freezing of cloud droplets at temperatures above their normal freezing-point (~-38 C), and at a relative humidity (RH) below the normal freezing RH of aqueous solution droplets at lower temperatures. These INP induced variabilities influence cloud lifetime, phase, as well as cloud optical and microphysical properties. Developing a relational model of INPs in global climate models has proven challenging as existing instrumentation systems either require too much air volume (in real-time flow instruments) or exhibit too much temperature variability (in off-line frozen assay based instruments).  Thus, there is a real urgency to address this unmet need.

Non-Mechanical Multi-Wavelength Integrated Photonic Beam Steering Device

Today, projecting optical energy is performed using high power laser sources coupled to free-space optical systems comprised of mechanical components, moving parts, and bulk optics. Unfortunately, the application range of these legacy systems is limited by their size, weight, reliability and cost. Consequently, a substantial research effort has been directed toward the miniaturization and simplification of these systems. Recent work has focused on beam steering using phased arrays. Although optical phased arrays are an elegant non-mechanical beam steering approach, the technical and environmental challenges compared to RF systems (10,000 times smaller wavelengths and tolerances) are daunting. Multi-octave operation across the UV to LWIR regions with acceptable losses poses additional technical challenge for any optical phased array beam steering approach. For these reasons, a need exists for a non-mechanical beam steering approach that lends itself to miniaturization as well as high power ultra-wideband operation.

A Digital LDO Employing A Switched-Capacitor Resistance

A low-dropout or LDO regulator is a DC linear voltage regulator that can regulate the output voltage even when the supply voltage is very close to the output voltage. The advantages of a low dropout voltage regulator over other DC to DC regulators include the absence of switching noise (as no switching takes place), smaller device size (as neither large inductors nor transformers are needed), and greater design simplicity (usually consists of a reference, an amplifier, and a pass element).
