Receive-noise analysis of capacitive micromachined ultrasonic transducers
Bozkurt, A.; Yaralıoğlu, Göksen Göksenin (IEEE, 2016)This paper presents an analysis of thermal (Johnson) noise received from the radiation medium by otherwise noiseless capacitive micromachined ultrasonic transducer (CMUT) membranes operating in their fundamental resonance ... -
Signal to noise ratio optimization for a CMUT based medical ultrasound imaging system
Zangabad, R. P.; Bozkurt, A.; Yaralıoğlu, Göksen Göksenin (IEEE, 2015)CMUTs offers key performance benefits compared to their piezoelectric counterparts. However, CMUTs are not widely adopted in commercial ultrasound imaging systems due to low signal to noise ratio (SNR) in the obtained ... -
Two cantilever based sytem for viscosity and density monitoring
Cakmak, O.; Ermek, E.; Kilinc, N.; Yaralıoğlu, Göksen Göksenin; Urey, H. (IEEE, 2015)Viscosity and density measurements in liquids in real-time is challenging. Previous MEMS based approaches use frequency sweeps for the purpose and those methods are slow and not real-time. We show that high precision ... -
Vertical cavity capacitive transducer
Yaralıoğlu, Göksen Göksenin; Ergun, A. S.; Bozkurt, A. (American Institute of Physics Inc., 2021-04-01)The capacitive micromachined ultrasonic transducer (CMUT) has inherent advantages, such as larger bandwidth and monolithic integration capability with electronics, when compared to the piezoelectric transducer. The most ...
