  • Piezoelectric transducer drive having temperature compensation
    Patent number: 4314174
    Abstract: A piezoelectric transducer drive for use within a ring laser gyro is shown wherein a resistive element is combined in a negative feedback loop with a second resistive element to provide a feedback signal which is constant with variations in the transducer material and linear with temperature change. The feedback signal is amplified and applied to a comparator whose output is modulated with an AC signal and applied to a power amplifier that drives the piezoelectric transducer for controlling the displacement thereof uniformly over a wide temperature range.
