In a temperature-compensated crystal oscillator wherein a temperature-compensated crystal oscillation circuit is driven by a constant voltage generation circuit, the constant voltage generation circuit comprises a differential circuit, a dc load for supplying feedback signals to the differential circuit, a first driver for driving the dc load under control of the differential circuit, a phase-compensation capacitor coupled between a control terminal of the first driver and an output terminal thereof and a second driver for driving the temperature-compensated crystal oscillation circuit. The second driver is the same kind of device as is used for the first driver, and is under control by the same control signal as a control signal for the first driver, sent out by the differential circuit.
