Abstract:
Implementations of a capacitive micromachined ultra-sonic transducer (CMUT) include a feedback component connected in series with the CMUT. The feedback component applies a feedback on a voltage applied on the CMUT for affecting the voltage applied on the CMUT as a capacitance of the CMUT changes during actuation of the CMUT.
