Design and experimental investigation of charge amplifiers for ultrasonic transducers
Hansen, Svein Kristian Esp (Master thesis; Mastergradsoppgave, 2014-06-02)Amplifiers are used in all types of electrical circuits to boost signal and there is a huge variety in designs used for different applications. For ultrasonic applications our group has previously used commercial available transimpedance amplifiers that converts a current to a voltage, but these amplifiers have a linear response over its frequency range. To preserve as much information as ...
