Patent ID: 10571436

Abstract:
An apparatus includes a transducer array with a plurality of CMUT elements. Each of the plurality of CMUT elements includes a first end and a second end. The transducer array further includes a bias network that is electrically connected with the first and second ends of the plurality of CMUT elements. The bias network applies a first bias voltage to the first end of the plurality of CMUT elements and a second bias voltage to the second end of the plurality of CMUT elements. The first and second bias voltages bias the plurality of CMUT elements. A method includes biasing, with bias network, a CMUT element of an transducer array using a bipolar signal that includes a first bias voltage and a second bias voltage, transmitting, by a transmit circuit, a transmit signal to the CMUT element, receiving, by a receive circuit, a receive signal from the CMUT element.
