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.
La présente invention est un dispositif générateur de signaux. Ce dispositif comprend un oscillateur à cristal et un inverseur connecté en parallèle avec cet oscillateur. Il est conçu de façon à ajuster l'amplitude du signal d'entrée de l'inverseur et de transmettre ce signal à un circuit amplificateur par l'intermédiaire d'un couplage capacitif pour l'amplifier. Il peut être construit de façon simple avec des bornes en nombre restreint, ce qui le rend approprié aux montages à grande densité ou aux circuits intégrés et en réduit facilement le prix de revient.
