In this paper, the authors present a design of a minimum phase noise current controlled oscillator in CMOS technology. Owing to their high degree of controllability, the second generation current ...

[Tom Hall], along with many hams around the world, have been hacking the Silicon Labs Si5351 to create VFOs (variable frequency oscillators) to control receivers and transmitters. You can see the ...

Any PN junction diode can be used as a variable capacitor in reverse biased mode, as well as in the forward biased mode before the knee voltage. The capacitance is usually very small as the junction ...

The FAN7621 resonant controller from Fairchild Semiconductor simplifies design, reduces bill of materials, and provides advanced protection functions, according to the company. It integrates a ...

Researchers have modeled how the combination of a virtual oscillator control mechanism and a cascaded sliding mode control can help regulate voltage and frequency in a distributed-solar microgrid.
