    • A temperature-adaptive capacitor array used in a TCXO so that the TCXO effectively conducts temperature-compensating in the resonant frequency without the non-monotonicity while a smaller silicon area is used in producing the capacitor array. A number of capacitor arrays allocated in two capacitor banks. Each of the capacitor arrays comprises two or more unit cells, and in turn each unit cell consists of a unit capacitor and a switching element, respectively. All of unit capacitors included in the capacitor arrays are connected each other through a decoder assembly to provide a crystal oscillator with a load capacitance. The unit capacitors belonging to one of the capacitor arrays have the same capacitance with each other. Two unit capacitors belonging to different capacitor arrays, however, have different capacitances from each other. The capacitance of the unit capacitors belonging to each capacitor array is set in consideration of control preciseness required in compensating a frequency deviation in the resonant frequency of the crystal oscillator as the temperature varies in at least a portion of a practical temperature range, within which the crystal oscillator operates.
    • 在TCXO中使用的温度自适应电容器阵列使得TCXO有效地在谐振频率下进行温度补偿而没有非单调性,而在生产电容器阵列中使用更小的硅面积。 多个电容器阵列分配在两个电容器组中。 每个电容器阵列包括两个或更多个单元电池,并且每个单元电池又分别由单元电容器和开关元件组成。 包含在电容器阵列中的所有单元电容器通过解码器组件相互连接以提供具有负载电容的晶体振荡器。 属于其中一个电容器阵列的单位电容器具有彼此相同的电容。 然而,属于不同电容器阵列的两个单元电容器具有彼此不同的电容。 考虑到当温度在实际温度范围的至少一部分中变化时补偿晶体振荡器的谐振频率中的频率偏差所需的控制精度,设置属于每个电容器阵列的单位电容器的电容, 晶体振荡器工作。
