This paper describes a CMOS mixer core, operating at 1GHz, where the RF signal is input via the bulk. The advantages of a bulk driven mixer are low power supply voltages and low power consumption. Simulations have confirmed that a power supply as low as 1V can be used to power the mixer core, which drains approximately 1.6mA. Although the mixer core consumes very low power, it still provides re...

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...

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 ...

In this paper, low voltage high gain up-conversion mixer, designed in 90nm CMOS technology, is proposed to work in the frequency band of 2.4 GHz. Current bleeding technique and current mirror topology are used in the upconversion mixer. Conversion Of an input of 100 MHz Given as intermediate frequency signal to an output of 2.4 GHz radio frequency signal is done by the proposed mixer with a loc...

Objective: In this article, a numerical study is conducted on mixing of two fluids in the liquid phase with two different concentrations of a chemical species in the electro-osmotic flow. Methods: The base liquid is an electrolyte which flows in a two-dimensional micro-channel having electrically charged walls.

The scaling of the CMOS technologies has a great impact on analog design. The most severe consequence is a reduction of the voltage supply. In this article, a new low-voltage folded-switching mixer with current-reuse, which operates at 1 V supply voltage, is discussed. The main advantages of the introduced mixer topology are: a high voltage gain, a low noise figure, an operation at low supply v...

We have applied an optimization method in conjunction with numerical simulations to minimize the mixing time of a microfluidic mixer developed for protein folding studies. The optimization method uses a semideterministic algorithm to find the global minimum of the mixing time by varying the mixer geometry and flow conditions. We describe the minimization problem and constraints and give a brief...
