| Abstract: | Working principle of VCXO is briefly introduced,as well as the crystal and capacitance variable diode,which plays the most important role in the VCXO.Then the parameters design of crystal and capacitance variable diode is discussed in detail to achieve the required voltage-controlled frequency deviation and linearity performance.Finally,several special voltage control circuits are described,which could realize negative slope voltage control characteristic and improve the voltage control symmetry performance. |

| Keywords: | VCXO voltage-controlled linearity voltage-controlled frequency deviation negative slope symmetry |
