Application: Driver circuitry for piezoelectric transducers (Patent ID: US20240074319A1)
The patent filed by Cirrus Logic Inc. describes circuitry for driving a piezoelectric transducer, including driver circuitry to supply a drive signal and active inductor circuitry that can be tuned to adjust the frequency characteristic of the output signal. The active inductor circuitry consists of gyrator circuitry and a capacitance, with adjustable transconductors and capacitance values to modify the operational frequency characteristics of the transducer. Additionally, the circuitry includes current monitor circuitry to estimate the impedance of the transducer and adjust the active inductor circuitry accordingly.
Furthermore, the integrated circuit described in the patent incorporates the driver circuitry and active inductor circuitry to drive the piezoelectric transducer and adjust its frequency characteristics. The active inductor circuitry can be tuned using gyrator circuitry with adjustable transconductors and capacitance values. The patent also covers a system with multiple piezoelectric transducers, each associated with driver circuitry and active inductor circuitry that can be tuned to provide different operational bandwidths for each transducer. Overall, the patent focuses on innovative circuitry design for driving piezoelectric transducers with adjustable frequency characteristics to optimize performance.
