Abstract
An assembly including a transducer, such as a capacitive transducer, a vibration sensor or a microphone, and an amplifier for receiving and amplifying an output of the transducer, where the amplifier is supplied with a voltage being at least 60% of a voltage corresponding to an electrical field between two elements of the transducer. When the transducer is a biased transducer, the amplifier is supplied with a voltage being at least 60% of a biasing voltage of the transducer.
