    Abstract
  • The noise properties of a preamplifier module directly influence the receptivity of a piezoelectric thin film transducer of polyvinylidence fluoride(PVDF). According to the characteristics of the PVDF piezoelectric film transducer, this paper designs a preamplifier module to match the transducer. Interferences and noises are eliminated by the anti-interfere technology applied for analog signal processing. The design factors of the preamplifier module are considered. The design module is simulated via the software Multisim12 and tested in laboratory. The results show that the input noise of this module is lower than –130, which infers that the designed preamplifier module meets the requirement of underwater acoustic signal processing equipment.
