Piezoelectric Ceramic Oscillator Using Damped Capacitance Elimination Technique
View through CrossRef
The temperature stability of a piezoelectric ceramic oscillator is improved, using the damped capacitance elimination technique, which is performed using an operational amplifier circuit.
In order to improve the temperature stability, an electrostatic capacitance such that its temperature characteristic can cancel a change of the oscillation frequency is also applied in the circuit.
The theoretical principle of the damped capacitance elimination circuit and the experimental results are described.
The circuit proposed here is effective in improving the temperature stability of the piezoelectric ceramic oscillator.
