Abstract
A sensor component is disclosed including a transducer and an electrical circuit disposed in a housing. The electrical circuit includes a bias voltage source coupled to a first electrode of the transducer. A non-inverting amplifier stage is coupled to a second electrode of the transducer. An inverting amplifier stage is coupled to an output of the non-inverting amplifier stage. A negative feedback path is located between an output of the inverting amplifier stage and the first electrode of the transducer. An electrical output signal of the transducer can be attenuated by applying an attenuation signal, based on a filtered electrical signal, to the first electrode via the negative feedback path.
