Paper Abstract

The interdigital piezoelectric transducers are used in the microsize membrane silicon sensors to the generation and detection of the ultrasonic wave. The wave generation and propagation depend on some external factors, and as a result the wave amplitude as well as the phase velocity of the propagation change. The system of the membrane sensor with ultrasonic wave Lambda type can be examined as a delay line. The application of the membrane sensors as a delay line which works in the generator close loop was presented. The equivalent circuit of the generator with the sensor was analyzed by means of the SPICE program.
