Abstract:
The low altitude breakthrough has become an important battle mode of modern war, which brings the huge difficulty for low altitude defense. The microwave technology is an effective method to detect the moving target in the low altitude. Taking the frequency modulation of microwave as basic principle, and combined the Doppler Effect which can measure the velocity information of target, a microwave detecting system based on twice mixing is established. Its composition and working principle are analyzed, and the circuits are designed. The laboratory experiment indicates that it is completely feas

Abstract:
AbstractOptical computing is needed to support Tb/s in-network processing in a way that unifies communication and computation using a single data representation that supports in-transit network packet processing, security, and big data filtering. Support for optical computation of this sort requires leveraging the native properties of optical wave mixing to enable computation and switching for programmability. As a consequence, data must be encoded digitally as phase (M-PSK), semantics-preserving regeneration is the key to high-order computation, and data processing at Tb/s rates requires mixi

GaAs Schottky barrier diodes are used in heterodyne receiver applications to frequencies as high as 4,000 GHz. The primary application that has driven this technology has been radio astronomy. However, other applications are now also very important, particularly studies of the constituents of the Earth’s atmosphere. This paper presents a summary of this increasingly important technology. The requirements that the diodes must meet and the benefits of GaAs Schottky devices are discussed.

Two design methodologies for realization of low frequency (less than 20 GHz) compact and low loss microwave idlers have been proposed in this paper. Such idlers can be used for realizing low frequency higher order (6X or more) harmonic mixers or multipliers on monolithic integrated technology. Low frequency higher order harmonic mixers or multipliers are generally avoided due to higher losses and board space consumed by multiple idlers. The present proposed methods of idler design are based on realization of idlers by combining distributed microstrip transmission line and lumped components. Th

Abstract:
Abstract DNA-based devices often operate through a series of toehold-mediated strand-displacement reactions. To achieve cycling, fluidic mixing can be used to introduce ‘recovery’ strands to reset the system. However, such mixing can be cumbersome, non-robust, and wasteful of materials. Here we demonstrate mixing-free thermal cycling of DNA devices that operate through associative strand-displacement cascades. These cascades are favored at low temperatures due to the primacy of a net increase in base pairing, whereas rebinding of ‘recovery’ strands is favored at higher temperatures due to the

Abstract For ultra-high speed communication systems at high center frequencies above 100 GHz, we propose a disruptive change in system architecture to address major issues regarding amplifier chains with a large number of amplifier stages.

Instead of scaling a classic homodyne transceiver system, we employ repeated amplification in single-stage amplifiers through positive feedback as well as synthesizer-free self-mixing demodulation at the receive

Abstract:
We present a new circuit design for adaptive offset cancellation in a fully differential 2.4 GHz CMOS direct conversion mixer. Our circuit structure is a modification of a Gilbert cell mixer in which offsets are cancelled by injecting cancellation currents into the legs of the mixer by dynamically varying the bias on the active loads. We present analysis and simulation results of our mixer with offsets present. Offsets create non-linearities in any circuit by differentially shifting the small-signal bias point of a matched pair; forcing once symmetrical transistors to operate in different bias

For the first method, a novel linearization scheme for CMOS double-balanced mixer based on the use of multi-bias dual-gate transistors is presented. In this technique, two intermodulation distortion components with proper phase relationship, generated by devices operating at different bias conditions, are added together to cancel each other for the improvement of mixer's linearity. The measured performance of a fabricated CMOS mixer operating at RF frequency of 2.45GHz and LO frequency of 2.35GHz is demonstrated.

Data Center hybrid air/liquid cooling systems such as rear door heat exchangers, overhead and in row cooling systems enable localized, on-demand cooling, or “smart cooling.” At the heart of all hybrid cooling systems is an air to liquid cross flow heat exchanger that regulates the amount of cooling delivered by the system by modulating the liquid or air flows and/or temperatures. Due the central role that the heat exchanger plays in the system response, understanding the transient response of the heat exchanger is crucial for the precise control of hybrid cooling system.

In the continuing effort to achieve better specific power and higher cycle efficiencies, gas turbine designers have through the years sought higher and higher firing temperatures. A large part of this gain in firing temperatures has been achieved through cooling the turbine nozzles and buckets. In almost all cases the coolant, usually air, is discharged into the gas path after performing its cooling function. This approach entails the double penalties of causing mixing losses and of producing a dilution of the hot gas stream by admixture of the lower temperature coolant. This paper presents a
