Crystal oscillators exploit the piezoelectric resonance of quartz or alternative piezoelectric materials to generate stable electrical frequencies with high quality factors. Fundamental design ...

Trying to use a JFET for that limiting proved disappointing. Even when the circuit was optimised to minimise its inherent non-linearity, it added about -92 dB / 0.0025% of third harmonic to the ...

Frequency multipliers are essential to generate a high frequency, low phase-noise signal from a low frequency, high performance oscillator. Figure 1 shows a phase noise comparison between a signal ...

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 ...

If there’s one thing that amateur radio operators are passionate about, it’s the search for the perfect sine wave. Oscillators without any harmonics are an important part of spectrum hygiene, and ...

Scientists have utilized a device based on the Duffing oscillator to solve the problem of PV systems’ low efficiency at low input voltages at dawn and sunset. Its performance was reportedly better ...
