摘要：
An amplifier circuit for amplifying output signal from the crystal oscillator circuit is connected to the output side of the crystal oscillator circuit. The amplifier circuit amplifies the difference between the output voltage of the crystal oscillator circuit and the input voltage of a CMOS inverter of the crystal oscillator circuit. For example, a differential amplifier is connected to the output side of the crystal oscillator circuit, then the output voltage of the crystal oscillator circuit and the input voltage of the CMOS inverter are connected to the inputs of the differential amplifier.
