Abstract
A temperature-compensated piezoelectric oscillator is disclosed. This oscillator comprises an oscillating circuit consisting of an amplifier, the output of which is looped back to the input through a piezoelectric resonator which is series mounted with a variable capacitance element, a circuit for the regulation of frequency according to temperature giving a compensation voltage and a circuit for frequency adjustment giving a variable in time resetting voltage, wherein the circuit for regulating the frequency according to temperature is connected to one of the terminals of the variable capacitance element through a means, the gain of which varies according to the resetting voltage delivered by the frequency adjusting circuit.
