摘要： Disclosed is a temperature-compensated piezoelectric oscillator (1) that is easily IC packaged and easily adjusted after assembly, and which is adapted to compensate for temperature dependent frequency changes of a piezoelectric vibrator (9) used as the oscillation frequency determining element without the need for an externally connected variable reactance element. The oscillator (1) comprises in addition to the vibrator (9), an oscillator circuit (8) for driving the vibrator (9), a temperature sensor circuit (2) for sensing the ambient temperature T, and a variable power supply circuit (15) for applying to the oscillator circuit (8) a power supply voltage VDD(T) which is controlled in response to the sensed temperature by the temperature sensor circuit 2 in such a way as to compensate the frequency-temperature characteristic of the vibrator (9).
