For years, engineers and scientists have been plagued by an extremely undesirable property of the quartz crystal unit-its significant frequency shift as a function of drive level for drive levels in ...

Tuning fork crystals, also known as wrist watch crystals, are one of the classical crystal design used for time control in watches, clocks, and other electronic devices. The most common frequency of ...

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 and ...
