An example actuator driver circuit generally includes a driver and calibration circuitry. The driver has at least one output for coupling to at least one input of an actuator. The calibration circuitry is configured to: detect a phase of a voltage signal at the at least one output of the driver, detect a phase of a current signal at the at least one output of the driver, determine a phase difference between the phase of the voltage signal and the phase of the current signal, and adjust a frequency of an oscillating signal for the driver, based at least in part on the phase difference."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Actuator driver circuit with self-resonance tracking","description":"Certain aspects of the present disclosure generally relate to methods and apparatus for driving haptic actuators.
