Frequent contributor Nick Cornford recently shared design ideas incorporating cool circuits for linear-in-pitch voltage-controlled oscillators...

In this second and concluding part, we will improve that circuitry and also add an audio output to allow us to hear the otherwise inaudible...

VLSI Solution announces VS1073, the world's most advanced audio codec coprocessor with earphone amplifier...

Electrets aren’t only used as audio pickups. For decades, they have been employed in security systems to detect unexpected changes of air pressure within rooms...

Figure’s circuit is not as fast as some other circuits, but its 2.5 MHz output settles from a full-scale input step in only 3 μs. This makes the circuit a good candidate for FM applications or any area where fast response to input movement is required...

A recent Design Idea, “Three discretes suffice to interface PWM to switching regulators”, demonstrated one way to use PWM to control the output of a typical switching voltage regulator. There were some discussions in the comments section about circuit behavior, which influenced design modification...

Toshiba Electronics Europe has launched a gate driver photocoupler suitable for driving silicon carbide MOSFETs in industrial equipment like industrial inverters, uninterruptible power supplies, and photovoltaic inverters...

In April 2012, EDN published a circuit by John Fattaruso that lets you quickly measure the drain-source saturation current and the pinch-off voltage of both an N-JFET and a P-JFET...

Quantum computers are among today’s most exciting emerging technologies, but their design, testing, and manufacturing require unparalleled care to avoid damaging their components...

Many different switching regulator topologies exist. Some, such as the classic stepdown converter, also known as a buck converter, are very widespread...
