In an ultrasound system, impedance matching between a transducer and an electronics is one of the crucial factors to determine the performance. An electronics must operate with different transducers, which have their characteristic impulse responses and widely varying impedances so that impedance matching is difficult. Also, the parasitic element is another factor that impedes the impedance matching. In this paper, using MATLAB and Simulink, we simulate a pulse-echo ultrasound system and the matching network which is required to allow the use of transducers with widely differing impedances. Our simulation includes models of the high-voltage transmitter, the transmission interface, the acoustic subsystem which includes wave propagation and reflection, the receiving interface, and the front-end receiver, as well as a lumped model of the matching interface which can easily be adjusted by the designer. The simulated pulse-echo behavior was in close agreement with experimental measurements.
