When tasked with a current sensing requirement, designers typically look first to using dedicated resistors designed for this task. Occasionally though there is the temptation to consider sensing current in a printed circuit board (PCB) trace...

Lace Lithography AS is developing a form of lithography that uses atoms fired at a surface to define features at resolutions beyond what is possible using extreme ultraviolet lithography...

The TL431 has been around for nearly 50 years. During those decades, while primarily marketed as a precision adjustable shunt regulator, this legacy device also found its way into alternative applications...

Diodes Incorporated introduces its first automotive-compliant 3D linear Hall effect sensor. The AH4930Q detects the magnetic field in the X, Y, and Z directions, allowing for reliable and high-precision contactless rotary motion and proximity detection...

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...
