Temperature compensation in a cmut device

CMUT devices are used in many applications e.g. for ultrasound imaging and pressure measurement. These devices operate by sensing a change in capacitance caused by deflection of a membrane comprising one of a pair of electrodes in the device by ultrasound exposure of, or pressure applied on, the mem...

Beschreibung
Zusammenfassung:	CMUT devices are used in many applications e.g. for ultrasound imaging and pressure measurement. These devices operate by sensing a change in capacitance caused by deflection of a membrane comprising one of a pair of electrodes in the device by ultrasound exposure of, or pressure applied on, the membrane. The CMUT device may be susceptible to the effects of changing temperature.
