Abstract:
The oscillator arrangement (1) comprises a differential amplifier (13) and also a first and a second terminal (2, 3). The first terminal (2) of the oscillator arrangement (1) can be coupled via a quartz resonator (10) to the second terminal (3) of the oscillator arrangement (1) and via a first capacitor (11) to a reference voltage terminal (8). The second terminal (3) of the oscillator arrangement (1) can be coupled via a second capacitor (12) to the reference voltage terminal (8). The differential amplifier (13) is connected at a first input (14) to the first terminal (2) of the oscillator arrangement (1) and at an output (16) to the second terminal (3) of the oscillator arrangement (1). The second input (15) of the differential amplifier (13) is connected via a direct voltage source (21) to the reference voltage terminal (8).
