Time-Offset Fractional-N PLLs for Heterodyne FMCW SAR
… counterparts, and enable certain inter-antenna feed-through suppression techniques. Despite these advantages, homodyne receivers are more prevalent owing to advantages in size, weight and cost. Designed to address this dilemma, the miloSAR is believed to be the only heterodyne FMCW SAR to employ …

Design and Characterization of RFIC Voltage Controlled Oscillators in Silicon Germanium HBT and Submicron MOS Technologies
… to address other system level effects, such as feed-through of the local oscillator (LO). LO feed-through directly results in self-mixing in direct conversion receivers, which gives rise to unwanted corrupting DC offsets. Therefore, a system-level strategy is employed to avoid such issues. For …

Responses of Rumen Microflora to Whey Products Added to High-Grain Low-Roughage Rations
<p>Many factors present in livestock feeds affect the numbers and types of protozoa and bacteria in the rumen. A small particle size of feed and a fast rate of passage of the feed through the ruminant decreases protozoal numbers. Full feeding of a concentrate ration and an acid pH in the rumen also …

Analysis of an Antineutrino Detector
… called CHANDLER. CHANDLER detects antineutrinos through inverse beta decay (IBD), using a highly segmented array of plastic scintillator segments to identify the positron through topology, and sheets of lithium-doped zinc sulfide to cleanly distinguish the neutron using pulse shape discrimination …

Towards integrated QPSK transceiver on zero-change CMOS foundry process
… Finally, double-coupled ring resonators with feed through waveguides are used for QPSK modulators. Carrier injection changes the resonance condition and provides phase shift. With the development of these devices, the path towards a monolithic QPSK transceiver in CMOS becomes clear.

Neural Network Enhancement of Closed-Loop Controllers for Ill-Modeled Systems with Unknown Nonlinearities
… the neural network, which is referred to as a "feed-through neural network." The initial unity gain causes the output of the neural network to be equal to the input of neural network at the beginning of the convergence process. The result is that the closed-loop system's performance with the …
