Abstract: A method of operating a capacitive ultrasonic transducer may include: applying a first driving signal to a first electrode to generate a transmission pulse voltage during a transmission period; and/or applying a second driving signal to a second electrode to generate a transmission bias voltage during the transmission period and a receiving bias voltage, different from the transmission bias voltage, during a receiving period. A method of operating an ultrasonic transducer, including a pair of electrodes receiving pulse and DC bias voltages, may include: modulating the DC bias voltage into a transmission bias voltage and superposing the transmission bias and pulse voltages so as to apply the superposed voltage to the electrodes in a transmission mode; and/or modulating the DC bias voltage into a receiving bias voltage, different from the transmission bias voltage, and applying the receiving bias voltage to one of the electrodes in a receiving mode.
