It’s not often that a single photo can tell you pretty much everything you need to know about a project, but the spectrum analyzer screenshot nearby is the perfect summary of this over-the-top ...

I recently had the opportunity to investigate a new micropower 6-MHz LTC6255 op amp driving a 12-bit, 250k sample/sec LTC2361 ADC. I wanted to acquire the FFT of a pure sinusoid of about 5 kHz. The ...

Of all the low-frequency oscillator configurations, the Wien Bridge has to be the friendliest and easiest to get along with. Like a faithful dog, it behaves itself regardless of the weather, is not ...

Way back when [Ms Ellsworth] was a kid, she kept seeing the same circuit over and over again in her various op-amp books. It was a Wien bridge oscillator, a small circuit that outputs a sine wave with ...

I can remember a colleague working for weeks on a sinewave generator board for a piece of test equipment. He came up with a Wein bridge oscillator with several refinements that had wonderfully low ...

After delving into Texas Instrument’s crystal-replacing bulk acoustic wave (BAW) oscillator recently, Electronics Weekly is taking a look at an advanced version of the humble RC oscillator, reported ...

Determine the value of C required for the Wien-bridge oscillator circuit with a sinusoidal oscillation frequency of 1 kHz. In a Wien bridge oscillator circuit, we must determine first if it provides ...
