Abstract: On an integrated circuit, a power limiting circuit is added to a crystal oscillator for limiting power dissipation in the crystal to a prescribed safe power dissipation range. The power limiting circuit includes a Pierce design crystal-controlled oscillator coupled to a self-stabilizing circuit. The self-stabilizing circuit detects the oscillation amplitudes of the crystal controlled oscillator. The self-stabilizing circuit prevents the oscillations from exceeding a predetermined maximum power dissipation level for the crystal. The self-stabilizing circuit includes a means for detecting oscillation amplitudes and means for limiting the gain of the crystal controlled oscillator circuit. Therefore, independent of manufacturing tolerances from integrated circuit to integrated circuit, the self-stabilizing circuit assures that the maximum power dissipation level of the crystal is not exceeded.
