Abstract
Ultrasound solutions are widely used in industrial and medical applications for distance measurements and imaging. A multiplexing switch unit is required to drive a piezoelectric transducer array for imaging by a single ultrasound pulse source. Higher frequencies are required for better image resolution. The necessary multiplexer has to handle these high driving voltages up to 100 V at high frequencies up to 100 MHz. The test environment and methodology for semiconductor multiplexer circuits are described in this article. The main focus is set on the generation of large test signals needed to drive the multiplexer.
Zusammenfassung
Ultraschall wird in vielen Bereichen von industriellen und medizinischen Applikationen zur Entfernungsbestimmung und für bildgebende Verfahren genutzt. Zur Ansteuerung eines piezoelektrischen Transducerarrays mit einer einzelnen Ultraschall-Impulsquelle wird eine Umschalteinheit benötigt. Für eine bessere Auflösung der Ultraschallbilder werden höhere Frequenzen erforderlich. Der benötigte Multiplexer muss diese hohe Ansteuerspannung bis zu 100 V bei Frequenzen bis zu 100 MHz schalten können. Die Testumgebung und -methodik für Multiplexer-Halbleiter-Schaltkreise wird in diesem Artikel beschrieben. Der Schwerpunkt wird auf die Generierung der Testsignale gelegt, welche zur Großsignal-Ansteuerung der Multiplexer-Schaltkreise dienen.
