21.twenty(a) is generally called the Pierce crystal. The resulting circuit frequency of oscillations is ready via the collection resonant frequency of your crystal. Variants in offer voltage, transistor parameters, and many others. don't have any effect on the circuit working frequency which can be held stabilized through the crystal.
