Abstract
A temperature compensated crystal oscillator has a crystal oscillating unit and at least one part for temperature compensation and oscillation circuits. The temperature compensated crystal oscillator has a layered structure and a planar thin film resistor. The layered structure has an upper layer on which the crystal oscillator and the part are mounted, and at least one layer on which conduction patterns are formed. The planar thin film resistor is arranged on an upper surface of a bottom layer of the layered structure so as to adjust an output frequency of the temperature compensated crystal oscillator. Therefore, an area occupied by the resistor for adjusting the output frequency can be minimized by inserting the resistor between the layers.
