WebParasitic oscillation is an undesirable electronic oscillation (cyclic variation in output voltage or current) in an electronic or digital device. It is often caused by feedback in an … WebThe parasitic oscillation is encountered when the varactor Vtune voltage drops below 3.9V. The loaded tank Q is very low at this point, and the oscillator then finds a very high-Q parasitic resonant path. This path is typically a series resonance path consisting of a very low loss series inductance resonating with the internal capacitance of ...
