(2) Changes of load capacitance and oscillation frequency  
As shown above, the series resonance frequency of the crystal  
unit changes with load capacitance CL of the oscillation circuit.  
In the actual oscillation circuit, however, fine adjustments of  
oscillation frequencies are carried out by varying CL by the  
trimmer capacitor or the like. The following figure shows an  
example of load capacitance characteristics. The slope of the  
characteristics varies depending on the frequency, shape, the  
number of overtone mode, etc.

The figure on the right shows a standard CMOS inverter crystal  
oscillation circuit for oscillating crystal unit with fundamental mode.  
* Rx is an element to reduce excitation current of the crystal unit  
preventing frequency fluctuation, but Rx is not used in some cases.

It is not desirable that the excessive increase of the value of  
condenser leads to a decrease of the negative resistance  
resulting in increasing the possibility of oscillation failure.

Frequency characteristics of negative resistance  
Rd mainly adjusts frequency characteristics of the negative  
resistance and is used to prevent oscillating by third Overtone  
mode. In case of a bigger circuit of the negative resistance,  
there is a case it is used to prevent the abnormal oscillation.
