A quartz crystal’s electrical equivalent model is that of a series tuned circuit in parallel with a capacitor, giving it some of the properties of both a parallel and a series tuned circuit.

The equivalent circuit of the quartz crystal appears like a series-parallel RLC circuit as shown below. Depending upon the circuit features, the crystal can act as a capacitor, an inductor, a ...

In comparison, the crystal oscillator is very simple and depends heavily on the very high “Q” quartz crystal resonator as the sole frequency-determining element shown in Figure 1c.. Both MEMS ...
