ABSTRACT:
A signal generating device according to the present invention is a device for generating a signal. The device includes a crystal oscillating element and an inverter connected in parallel with the crystal oscillating element. The device is arranged to adjust the amplitude of a signal produced at an input side of the inverter and to capacity-couple the signal produced at the input side of the inverter to an amplifier circuit so that the signal produced at the input side of the inverter is amplified. Accordingly, it is possible to realize a simple construction which includes a reduced number of terminals, which is suited to high-density mounting or is suitably formed as an integrated circuit, and which can be easily reduced in cost.
