Temperature stabilizer and oscillating apparatus

Abstract

A temperature stabilizer for accurately stabilizing the temperature of an object is provided. The temperature stabilizer stabilizes the temperature of an object to a reference temperature. The temperature stabilizer includes an oscillator provided in proximity to the object, for generating an oscillation signal having a frequency corresponding to an inputted frequency control signal, a phase detector for detecting the phase difference between a feedback signal based on the oscillation signal and a reference clock signal having a predetermined frequency, a loop filter for generating the frequency control signal to synchronize the feedback signal with the reference clock signal based on the output from the phase detector, a comparator for comparing the value of the frequency control signal with a reference value determined corresponding to the reference temperature and an electric heating converter for heating or cooling the object based on the comparison result from the comparator.
