Abstract
An oscillator circuit arrangement comprises a gain stage and a feedback loop that includes a crystal device. A clock signal monitor circuit is connected to an output of the gain stage and detects a frequency shift in the clock signal or a loss of oscillation. The current through the gain stage is controlled in response to a control signal generated by the clock signal monitor circuit.
