By Tahmid, EDAboard.com forum member SMPS is the toughest section in power electronics. For this subject, you require additional knowledge for choosing the active and passive parts used in SMPS circuits. The special type of parts often required in power electronics (i.e. for low-frequency applications) may not be suitable in the case of SMPS. When […]

Eye and Constellation Diagrams, Pt 1
Digital signals representing data symbols may be presumed to be clean, consistent representations of ones and zeroes when they are launched onto their communications medium, whether it is a wired, wireless RF, or optical fiber link. However, due to bandwidth limitations of the medium, external and internal noise, crosstalk, multipath, reflections, and many other unavoidable […]
Expanding I/O with MUX, DEMUX, and decoders
The relentless march of technological progress has given engineers increasingly smaller and more energy efficient microcontrollers to use in their designs. These benefits do come with a cost, however. Physically smaller packages have less room for I/O pins meaning fewer peripheral components can interface with the microcontroller itself. Fewer peripherals means less functionality which tends […]
Researchers say sliding-mode algorithm cleans up ripple in buck converter output
A special kind of control technique is said to be effective at eliminating voltage ripple in the output of buck converters that see a wide range of inputs. The design comes from scientists at Golestan University in Iran, Concordia University in Canada, and Delft University of Technology in the Netherlands. The researchers published their study […]

Choosing a reference voltage for an ADC
Analog-to-digital converters (ADCs) need a reference voltage (VREF) input in order to operate properly. ADCs convert analog inputs that can vary from zero volts on up to a maximum voltage level that is called the reference voltage. The reference voltage determines the ceiling of what the ADC can convert, and is essentially the yardstick against […]
Cheapest source of power? NREL says it might be solar
The levelized cost of energy (LCOE) for some kinds of solar and wind power can be cheaper than that for conventional gas-fired power plants. That is one conclusion to be had from the 2017 edition of the National Renewable Energy Lab’s Annual Technology Baseline (ATB) which summarizes the current and projected technology cost and performance […]
