Often, one needs a simple low voltage sinusoidal oscillator with good amplitude and frequency stability and low harmonic distortion; here, the Peltz oscillator becomes a viable candidate...

Targeting industrial and energy applications with motor drives for air conditioning, home appliances and factory automation, as well as power control in charging stations, energy storage systems, and power supply units STMicroelectronics’ STGAP3S family of gate drivers for silicon-carbide and IGBT power switches...

Implementation details Loop area R1/C1/R3 should be minimized for best EMI rejection. Additionally, R1/C1 should be very well shielded from electrical fields, which will be discussed further in the EMI Considerations section...

In the early days of personal computers, incorporation of one or two (or more) RS-232 serial ports as general purpose I/O adaptors was common practice...

The oscillator was intended for other purposes, but unexpectedly its breadboard prototype became in great demand for evaluating the performance of operational amplifiers purchased on well-known Internet sites...

A variety of analog front-end functions typically assist ADCs to do their jobs. These include instrumentation amplifiers, digitally programmable gain, and sample and holds. This circuit is a bit atypical in merging all three of these functions...

Noise in electrical circuits is typically the enemy, and any self-respecting circuit should output as little noise as possible. Nevertheless, there are cases where a well-characterized source of noise with no other signal is entirely the desired output...

Modern day recording and broadcast is a mixed bag for today's audio engineers when it comes to input signal chains. Microphone electronic technology really hasn't changed that much over the last 50 years...

An electronic dice is always an enjoyable project, which is easy to implement with some lines of program code on a microcontroller, or with a few digital components. However, implementing an electronic dice in analog technology is more of a challenge...

Piezoelectric actuators are excellent fast and precise means for generation and control of micro, nano, and even atomic scale movement on millisecond and faster timescales. Unfortunately, they are also excellent high-Q resonators...
