Abstract
Circuitry to automatically compensate a differential output oscillator circuit for common mode disturbances that may affect the oscillator output. For any differential oscillator the common mode voltage excursion may reduce the oscillator output, which in some examples may negatively affect the circuitry receiving the oscillator output. The addition of feedback circuitry with an automatic gain control, e.g., to regulate the differential output voltage, may further reduce the gain of the oscillator in the presence of common mode voltage. In contrast, the feedback circuitry of the oscillator circuit of this disclosure may include gain control circuitry to increase an output voltage amplitude at the differential output terminals for a duration of the common mode disturbance.
