Temperature compensated crystal oscillator |
摘要 |
A temperature-compensated crystal oscillator for correcting frequency variations caused by temperature changes by means of a differential amplifier which detects an unbalanced voltage in a bridge circuit including a temperature sensitive element for controlling a capacitance of a variable capacitor. The oscillator includes a circuit element having a temperature characteristic responsive to a temperature characteristic of the variable capacitor. The aforesaid circuit element is positioned in a current sink path of the differential amplifier.
