Abstract
A semiconductor device includes a resistor element connected to one and another end of a crystal oscillator, and an adjustable current type inverter element having an input connected to one end of the resistor element and an output connected to another end of the resistor element. A first capacitor element is connected to the input of the inverter element and to ground, and a second capacitor element has one end connected to ground. A first switching element switches a connection state of the one end of the first capacitor element and another end of the second capacitor element. A third capacitor element is connected to the output of the inverter element and to ground, and a fourth capacitor element has one end connected to ground. A second switching element switches a connection state of the one end of the third capacitor element and another end of the fourth capacitor element.
