WebPutting a crystal in parallel with the feedback resistor creates a path where signals at a certain frequency are phase-shifted 180 degrees. Adding that to the inversion (equivalent to another 180 degree phase shift) gives …
Webchanical crystal. The mechanical res-onance is fundamentally represented by a series RLC branch, with a resistor modeling the loss [Figure 3(a)]. These components are called the “motional” resistance, inductance, and capaci-tance of the crystal, respectively. With this series branch, the crystal can act as a short circuit at resonance.
