Abstract
In the oscillator, a quartz crystal resonator and an oscillation circuit formed in an IC incorporating an inductor are electrically coupled to each other with a resonator interconnection disposed on a surface of a substrate to form an oscillation loop. A conductor layer disposed as an intermediate layer of the substrate is disposed so as to overlap the resonator interconnection and not to overlap the inductor incorporated in the IC in a plan view.
Claims10
An oscillator comprising:
- an integrated circuit element having an oscillation circuit to electrically be coupled to a resonator element, and an inductor;
- and
- a substrate having a first surface on which the integrated circuit element is disposed, and on which a resonator interconnection to be coupled to the resonator element and the oscillation circuit to constitute an oscillation loop is disposed, and a second surface as an opposite surface to the first surface, wherein
- the substrate has a conductor layer between the first surface and the second surface, and
- the conductor layer overlaps the resonator interconnection, and does not overlap the inductor in a plan view.
