Beschreibung
Zusammenfassung:	An integrated circuit apparatus includes an oscillation circuit that generates an oscillation signal by using a resonator, an output buffer circuit that outputs a clock signal based on the oscillation signal, a DC voltage generation circuit that generates a DC voltage used to generate the oscillation signal or the clock signal, a power source pad to which a power source voltage is supplied, a ground pad to which a ground voltage is supplied, and a clock pad via which the clock signal is outputted. The ground pad and the DC voltage generation circuit are disposed so as to overlap with each other in the plan view.
