The original Mixer corpus was designed to satisfy developing commercial and forensic needs. The resulting Mixer corpora, Phases 1 through 5, have evolved to support and increasing variety of research tasks, including multilingual and cross-channel recognition. The Mixer Phases 4 and 5 corpora feature a wider variety of channels and greater variation in the situations under which the speech is r...

Intermodulation distortion (IMD) suppression is a critical issue in modern military and commercial RF/microwave systems. Pressed by the demands imposed by distortion-sensitive digital modulation formats, modern systems routinely specify linearity requirements that are impossible to attain using conventional approaches. To meet these new challenges, Marki Microwave has introduced the Two-Tone-Te...

We have realized an innovative integrated detector for electron spin resonance spectroscopy. The microsystem, consisting of an LC oscillator, a mixer, and a frequency division module, is integrated onto a single silicon chip using a conventional complementary metal-oxide-semiconductor technology. The implemented detection method is based on the measurement of the variation of the frequency of t...

This mixer is based on a passive FET resistive frequency converter cell described by first described in the literature by Steven Maas [ ] and explored by Wes Hayward and others [ ]. One difficulty with a DFET passive mixer is obtaining negative gate bias. This has been achieved using gate conduction as in the TriQuint 5M31 [Campbell, Criss], a LO frequency driven negative voltage converter as i...

A new CMOS active mixer topology can operate at 1 V supply voltage by use of SCM (switched currentmirror). Such current-mode mixer requires less voltage headroom with good linearization. Mixing is achieved with four improved current mirrors, which are alternatively activated. For ideal switching, the operation is equivalent to a conventional active mixer. This paper analyzes the performance of ...

Micromixing in a static mixer and an empty tube was characterized by the product distribution of fast consecutive competing reactions. As a test reaction, the precipitation of barium sulphate complexed by EDTA in alkaline medium under the influence of an acid was used. The acid was injected at a point of the reactor into an excess of basic complex. The precipitated BaSO4 is a measure for the de...
