Beam forming device and system including the same

A probe system comprising:

• a plurality of transducers configured to convert signals received from a plurality of channels to a plurality of analog signals;
• and
• a beam forming device configured to receive the plurality of analog signals and to output a digital signal which is a conversion of an analog beam signal corresponding to a combination of the plurality of analog signals,
• wherein the beam forming device comprises:
• a signal storage circuit configured to receive the plurality of analog signals to store the analog beam signal corresponding to a combination of the plurality of analog signals;
• and
• a control circuit configured to control the signal storage circuit so that the signal storage circuit receives the plurality of analog signals and stores the analog beam signal, to generate a digital signal corresponding to the analog beam signal and to control the signal storage circuit so that an output voltage of the signal storage circuit is updated while the digital signal is being generated.
