Abstract:
    The invention provides an integrated quartz oscillator circuit is disclosed having a capacitive voltage divider, which has a first capacitor and a second capacitor, as well as having a first transconductance amplifier, which is placed in a loop connecting a first terminal and a second terminal of the first capacitor. An input of the first transconductance amplifier is connected to a center tap between the first capacitor and the second capacitor, an output of the first transconductance amplifier is connected to the first junction of the first capacitor, and the quartz oscillator circuit has a conductive element connected parallel to the second capacitor.
