Amplifiers are critical for ECG accuracy
The new generation of function-rich Electrocardiograms (ECGs) relies on high levels of accuracy to deliver advanced functions and amplifier selection plays a vital role in delivering these.Kevin Tretter, Microchip TechnologyECG basicsThe core function of a Electrocardiogram (ECG) is to measure the voltage potentials across the body, which are created with each contraction of the heart wall. The ECG then conditions the cardiac signals and outputs them as waveforms, either onto a display screen or as a print-out. For basic ECGs ... more
South-East European PV Market Review
South-East European PV Market ReviewPV markets have never performed so well in their entire history. While the awareness about the PV’s capabilities grows in the public opinion, it now appears on the energy map of several countries. The total of newly installed capacity added in 2010 represents in average the electricity production of two large coal-fired power plants. In several countries, grid parity for residential systems is reachable in the coming years. In some specific cases in countries or regions ... more
Precision op amp architectures
Not all precision op amps are created equal: benefits of different precision op amp architectureKevin Tretter, Microchip TechnologyWhilst there is little doubt that higher-precision operational amplifiers (op amps) can eliminate the need for system calibration, either during manufacturing or in the field, designers still face a choice of which low-offset architecture is best for each application. Choosing the right op amp means assessing the advantages and disadvantages of each type of architecture. This article outlines the pros and cons of ... more

Printing Makes Prominent Appearance in Photovoltaics
Printing is not a new concept for the photovoltaic (PV) industry. In fact, it has relied on screen printing to create the top electrodes for crystalline silicon (c-Si) PV for some time. An obvious next step is to use functional printing to create the core PV layer itself. The reason why a solar cell firm would want to do this is primarily one of cost. Although PV producers might be loath to admit it, at any given efficiency level, their ... more
Wind power potential in Romania, Bulgaria, Serbia and Turkey
Wind energy have proven to be attractive for several reasons – wind is plentifully available, it is cheap and virtually inexhaustible source of energy, and does not cause environmental damage or climatic anomalies. Operational costs for generation of energy, or rather the absence of fuel supply costs, does make wind an especially attractive energy source in the eyes of investors.In 2009, 39% of all new electricity generating capacity built in the European Union was wind power, ahead of coal, gas ... more
