A study on estimation of frequency aging for rectangular AT-cut resonators

This paper suggests estimate method of frequency-aging characteristic for the purpose of improving stabilization of frequency-aging characteristic of crystal resonator. This is the method in which change of quantity is calculated using estimated formula for every factor of frequency change from data of frequency-aging characteristic and by analyzing the temperature dependence. As such, this method enables frequency-aging characteristics in resonators to be estimated and evaluated with greater speed and accuracy.
