There are many parameters to consider when designing a circuit using an operational amplifier (op amp) including the op-amp’s gain bandwidth (GBW) product, offset voltage and quiescent current. In ...

Capacitive sensors are found in a wide range of equipment, from consumer electronics to industrial/process control. Touch buttons are increasingly found in lamps and dimmers. Motion detectors can ...

At low frequency, a transmission line, open at one end, looks like a capacitor. After all, it is just two conductors, the signal path and the return path, with some insulation between them. This is ...

If you enjoy building radio projects you may have noticed something slightly worrying over the last few years in your component supply. Variable capacitors are no longer as plentiful as they used to ...

In back-end semiconductor processing it is important to improve the performance of semiconductors due to the limitations of miniaturization in front-end processes. To achieve this goal, the industry ...

The inside of classic radios holds wonders that the sterile chips and SMD components of today’s circuits can’t hold a candle to. Chunky resistors and capacitors, vacuum tubes with cathodes aglow, and ...

Power system designers are constantly under pressure to attain larger power densities and improved conversion efficiencies, whether it is for data servers for the internet of things or data centers.
