Enhancement MOSFETs
FET transistors are working differently than BJT transistors. In FET width of conducting channel is varied by applying of external electric field. They operate…
Nanoelectronics: Photovoltaics
Photovoltaic (PV) systems are electrical systems, converting the energy from sunlight into electrical energy. This technology showed up at the beginning of the last century,…
Fields in transmission lines
Let's consider the general case of electromagnetic waves propagation in transmission lines. Transmission lines can be cylindrical with a parallel core, or can be…
Analogue-to-digital and digital-to-analogue signal conversion
This post covers the topic "AD and DA conversion explained". Digital-to-analogue (DAC) conversion converts binary words into voltage or current signal. And it's extreme…
Comparators
This post explains the difference between comparator and schmitt trigger. A comparator is a circuit with two inverting or non-inverting terminals and an output…
Data transmission
Data transmission is one of the important steps in data acquisition, and that data is usually transmitted in digital form. The most significant reason…
Nanoelectronics: CVD process for the heterostructures formation
CVD (or Chemical Vapour Deposition) of a solid on a heated surface from a chemical reaction in a vapour phase. This is a process…
How does molecular beam epitaxy work
This post answers the question "How does molecular beam epitaxy work?". Molecular beam epitaxy (MBE) is the technique of semiconductor material growth - a…
