The process of preparing feed mixtures using additives is a biotechnical system with deterministic relationships technological and technical economic characteristics, group input, disturbing, control output factors, taking into account which it necessary to determine the rational machine technology, structure operations corresponding solutions that are embedded in design unit. To describe proce...

A design for a subwavelength all-optical frequency mixer is proposed. The method relies on enhanced difference-frequency generation, which is achieved in two steps with the help of plasmonic nanoantennas. The interaction of the two input signals with the nonlinear material is increased through the use of input nanoantennas, which focus the incident energy of two different frequencies onto the n...

A new concept, the Bit-Mixer is introduced. It is a function of fixed, possibly different size of input and output, which computes statistically uncorrelated output from correlated input values, and its behavior is altered by parameters, called keys. Several constructions are presented, with very fast, power efficient implementations in electronic hardware, having very little side channel leaka...

There is a strong interest in the Submillimeter community to increase the IF bandwidth of SIS receivers in order to facilitate extra-galactic astronomy. However, increasing the IF bandwidth generally also means increasing the IF operating frequency of the mixer, because it is very difficult to achieve a good IF impedance match to a low noise amplifier (LNA) for more than an octave bandwidth. Co...

A 200-280 GHz RF front-end of transmitter is demonstrated in 65-nm CMOS. Saturated EIRP is greater than -5dBm over a frequency range of 60GHz. When the input power is -20dBm, EIRP is greater than -10dBm for most of the frequency range, and achieves 3-dB and 6-dB bandwidths of 24% and 33%. The front-end was integrated with a fractional-N synthesizer to form a transmitter operating at 208-255GHz ...

Today’s communication systems make strong demands on both receiver sensitivity and large-signal performance (dynamic range). When selecting components for a new design, therefore, it behooves the designer to focus on the performance of each one with regard to these requirements. In particular, this article deals with mixers and the basic parameters specified in their data sheets. The communicat...

Today's communication systems, such as wireless base stations, make strong demands on receiver sensitivity and large-signal performance. This article focuses on mixers, and describes key mixer performance issues and the basic parameters specified in data sheets. The article explains how to select the best mixer to optimize the receive channel. This article was also featured in Maxim's Engineeri...

Spectrum analysis is very essential requirement in instrumentation and communication signal interception. Spectrum analysis is normally carried out by online or offline FFT processing. The Goertzel algorithm is a digital signal processing (DSP) technique for identifying frequency components of a signal. While the general Fast Fourier transform (FFT) algorithm computes evenly across the bandwidt...

res of SIS receivers now in the range 2-4 times the ), the overall sensitivity of radio astronomy sly degraded by atmospheric noise, and sometimes by cillator source. In spectral line measurements, wanted (image) sideband can be eliminated by using an o reduce local oscillator noise, balanced mixers can ealize image separating and balanced mixers using RF circuits, but they are difficult to fab...

We present a design of a microfluidic mixer based on hydrodynamic focusing which is used to initiate the folding process (i.e., changes of the molecular structure) of a protein. The folding process is initiated by diluting (from 90% to 30%) the local denaturant concentration (initially 6 M GdCl solution) in a short time interval we refer to as mixing time. Our objective is to optimize this mixe...
