If you want to replicate the music of your favorite musicians, you will need to know the pedal effect devices they use and the circuitry within them. Furthermore, if you want to design new pedal ...

Any X-Y switch matrix can be considered with this circuit, which simplifies decoding of the common 4x4 keypad matrix and eliminates having to scan rows or columns. Using eight digital inputs, this ...

Lighting a string of LEDs at a constant brightness requires driving it with a regulated current. A boost converter is commonly used to step up the voltage to a level high enough to bias the LEDs on ...

Abstract: A simple circuit design technique for the realization of compact low-voltage low-power CMOS four-quadrant analog current multiplier circuit has been suggested. It is based on the use of the ...

When I was recently debugging a design, I discovered that a short circuit existed from a ground plane to a power plane. I did not have access to a milliohmmeter or an equivalent tester for locating ...

An RC circuit in series with the coil allows full-current turn-on for reliable relay operation, then reduces the current to save power. Fellow engineer Sanjay R. Chendvankar of Mumbai, India, recently ...

A relatively simple circuit invented by researchers at the University of Texas could let smartphones and other wireless devices send and receive data twice as fast as they do now. This circuit could ...

Abstract: Thermoelectric power generation modules for industrial applications often require an output of several tens of watts, and DC-DC converters used for power matching are required to have high ...
