    • A temperature-compensated crystal oscillator utilizing a fundamental frequency crystal with an input RC network to bias an input transistor. Temperature compensation for the oscillator is achieved by the use of a series diode in the emitter circuit of the input transistor. As the temperature changes, the emitter-to-base voltage varies and causes the emitter current to vary in the opposite direction. The voltage across the series diode tracks with the emitter-to-base voltage in the same direction. With these occurrences, the emitter-to-collector voltage is controlled and stabilized over a range of temperature changes. The parallel RC circuit which couples the input transistor to the output drive transistor provides the necessary base current and input impedance for the output trnasistor to permit saturation of and wave shaping by the output drive transistor.
    • 利用具有输入RC网络的基频晶体的温度补偿晶体振荡器来偏置输入晶体管。 振荡器的温度补偿通过在输入晶体管的发射极电路中使用串联二极管来实现。 随着温度的变化,发射极到基极电压发生变化,并使发射极电流沿相反方向变化。 串联二极管的电压跨过发射极到基极电压相同的方向。 在这些情况下,发射极 - 集电极电压在温度变化范围内被控制和稳定。 将输入晶体管耦合到输出驱动晶体管的并联RC电路为输出三极管提供必要的基极电流和输入阻抗,以允许输出驱动晶体管的饱和和波形整形。
