In this paper, a low power and high CMRR Instrumentation Amplifier is presented. It has been designed for use in Bio-Impedance (BI) applications that operate within the beta dispersion frequency range. An IA with a high CMRR and input impedance allows the extraction of the low amplitude BI signal while reducing the error signals and noise associated with the tissue and instrument interface. The...
Received Jan 2, 2017 Revised Mar 2, 2017 Accepted Mar 16, 2017 This paper relates the new topology and simulations of a fully differential CMOS active filter for mm wave band applications. The advantages of the differential topology over the single ended one are discussed and the quality factor is tuned to insure application requirements, including narrow bandwidth and high selectivity due to a...
Two Capillary Zone electrophoresis (CZE) methods were developed in this study, one using an acidic buffer (sodium citrate pH = 2.5) and the other using a basic buffer (sodium tetraborate pH = 9.8). The two methods were compared on the basis of repeatability and reproducibility of results and the CZE method developed with the basic buffer was then selected for further studies. The method was ful...
This paper discusses the design, analysis and performance of a 2.4 GHz fully integrated low-power current-reused receiver front-end implemented in 0.18 μm CMOS technology. The front-end is composed of a single-to-differential low-noise amplifier (LNA), using high-Q differential transformers and inductors and a coupled switching mixer stage. The mixer transconductor and LNA share the same DC cur...
We consider optimal control of a stochastic network, where service is controlled to prevent buffer overflow. We use a risk-sensitive escape time criterion, which in comparison to the ordinary escape time criteria heavily penalizes exits which occur on short time intervals. A limit as the buffer sizes tend to infinity is considered. In [2] we showed that, for a large class of networks, the limit...
In the pharmaceutical industry, cryoprotectants are added to buffer formulations protect active ingredient from freeze- and thaw damage. We investigated freezing thawing of aqueous sodium citrate with various cryoprotectants, specifically amino acids (cysteine, histidine, arginine, proline lysine), disaccharides (trehalose sucrose), polyhydric alcohols (glycerol mannitol) surfactants (polysorba...
