Abstract: A method for determining and mitigating over-excursion of an internal mass of an electromechanical transducer may include measuring a sensed signal associated with the electromechanical transducer in response to a driving signal driven to the electromechanical transducer, determining a non-linearity value based on the sensed signal, mapping the non-linearity value to a probability of over-excursion of the internal mass, and applying a gain to a signal path configured to generate the driving signal based on the probability.

Abstract: The disclosure relates to integrated circuits and methods of manufacture. A method involves forming a first set of one or more circuit layers on a semiconductor substrate, placing at least one prefabricated layer portion onto the first set of circuit layers to form a component, and forming a second set of one or more circuit layers over the first set of circuit layers and the at least prefabricated layer portion. The prefabricated layer portion may be a magnetic layer portion placed to form a magnetic component such as a magnetic core of an inductor or transformer. The method may also comprise forming the prefabricated layer portion.
