Abstract
A passive beamformer for ultrasound imaging. An ultrasound probe includes a plurality of ultrasound transducers and beamforming circuitry. Each of the ultrasound transducers is configured to convert ultrasonic signal into electrical signal. The beamforming circuitry is coupled to the plurality of ultrasound transducers. The beamforming circuitry includes a plurality of passive delay circuits and a passive hold circuit. One of the passive delay circuits is coupled to each of the ultrasound transducers. The passive hold circuit is coupled to the passive delay circuits to store a sum of the charges received from the delay circuits.
