“…Hirsekorn et al [10] perform numerical simulations of acoustic wave propagation through sonic crystals consisting of local resonators using the local interaction simulation approach (LISA). The current work applies the approach of Püttmer et al [7] to liquids and piezoelectric transducer to obtain an electrical analogue of one-dimensional, acoustic wave propagation through such materials. In order to keep things at a manageable level, the following simplifications and assumptions are made.…”

The system for simulation, measurement, and processing in Graphical User Interface implementation is presented. The received signal from the simulation is compared to that of an actual measurement in the time domain. The comparison of simulated, experimental data clearly shows that acoustic wave propagation can be modeled. The feasibility has been demonstrated in an ultrasound transducer setup for material property investigations. The results of simulation are compared to experimental measurements. The simulation result has good agreement with the experimental data which confirms the validity of the model. The simulation tool therefore provides a way to predict the received signal before anything is built. Furthermore, the use of an ultrasonic simulation package allows for the development of the associated electronics to amplify and process the received ultrasonic signals. Such a virtual design and testing procedure not only can save us time and money, but also can provide better understanding on design failures and allow us to modify designs more efficiently and economically.

AbsractThis paper describes the design of the complete transmit and receive electronics circuitry for a piezoelectric transducer in one single ASIC. The chip will be one building block in a thumb size battery operated ultrasound measurement system. The main design target has been to achieve extremely low power consumption while keeping the number of external components minimal.To overcome the dynamic range limitations imposed by a battery supply an on-chip boost converter uses one external inductor to generate up to 40 V for excitation of the transducer. The transducer itself is used as a storage capacitor, whereafter it is rapidly discharged to generate an ultrasound pulse. An on-chip amplifier with intermittent operation is controlled by a state machine and used to amplify incoming echoes. The chip has been fabricated in a 0.8 m high voltage CMOS process, with a total chip area of 12 mm 2 . Measurements verify the design approach. The power consumption for the system reaches within a factor of 2 of the power needed to charge the capacitance of the piezoelectric transducer from a fixed voltage source. The results show the possibility to achieve extremely low power consumption in a battery operated pulse-echo ultrasound measurement system.

“…Initially developed in [1], [2], [3], they were further improved by the introduction of controlled sources in order to avoid transformers and negative capacitances [4]. Mechanical and viscoelastic loss have been introduced to model low Q transducers [5]. The effect of material properties on viscoelastic loss was further investigated in [6] to improve the accuracy of the models regarding loss and wave speed.…”

Incorporation of mechanical noise in the SPICE model of a piezoelectric transducer

SPICE models of a piezoelectric device and the ultrasound propagation medium can be used in a simulator intended for electronic circuits and IC design to make efficient system level optimizations. This paper presents the inclusion of mechanical noise in the SPICE model of an ultrasound system. The modeling of the noise is based on the mechanical thermal noise which is equivalent to electronic Johnson (thermal) noise. For a system with a high-Q piezoelectric device designed into a medium-Q transducer the main energy loss, and thus also the main noise contribution, will occur in backing and sound propagation media. Thus, the modeling of the mechanical noise is performed by including electrical noise generation in the resistors that model these media in the electrical equivalent circuit. The resulting output voltage noise follows theoretical derivations of transducer noise as published by Farlow and Hayward. Simulations of a 4 MHz Pz27 piezoelectric disc with a diameter of 8 mm give a peak spectral noise density over 1 nV / √ Hz, which is comparable to that achievable with low-noise preamplifiers.
