Integrate circuits technology allows creating many types of devices on the silicon die. The most common devices are transistors, diodes, resistors or capacitors. Now, the different kinds of capacitors that could be integrated on-chip are discussed in this article.
A LabView sketch was used to simulate the stochastic signals and evaluate the functionality of the autocorrelation function and the spectral power density.
There are many of Integrated Circuit Design companies around the world, most of them nowadays fabless. Many of them tend to be located together or very near.
It is very common with the students, which are trying to learn a new programming language, to only read and understand the codes on the books or online. But until you don’t put hands on and start typing your own small programs, compile them, find errors, simulate, etc you will not get the experience to write your own codes and therefore to learn how to program a new language.
The scanning tunnelling microscopes have become the eyes of the scientists, a necessary and essential tool in the laboratories of education and research for the characterization of nanoscale. This article presents the basics of a tunneling microscope that have allowed scientists the visualization and modification of nanoscale surfaces. A methodology for the correct visualization and characterization of surfaces is described using the implemented instrument, reaching the bidimensional quantification of characteristics. This methodology, determined experimentally, takes into account critical parameters for stabilization of the tunnel current, such as the scanning speed and the geometries and dimensions of the microscope needles.

The eHealth sensor board is a nice development platform to explore the biomedical sensors, but it have many drawbacks in terms of low reliability of the sensors. Depending on the application this sensor board can be adequate or not. [Read more…] about How to connect the eHealth via Bluetooth with Python to a Computer
