Abstract:
The disclosure describes soft limiting electrical signals generated by a transducer before amplification, buffering or other signal conditioning in a microphone assembly, circuits and methods therefor. The soft limiting circuit includes a first circuit portion that limits a first portion of the electrical signal with reduced distortion when the first portion of the signal exceeds a threshold. A second circuit portion of the soft limiting circuit similarly limits a second portion of the electrical signal. In this way, overloading of an amplifier is avoided without excessive distortion.
