  • Patent number: 9986976
    Abstract: Various embodiments include a system and method that enhance performance of an ultrasound system by dynamically changing an impedance of a transmit/receive switch. The system can include a transmit/receive switch and a low noise amplifier. The transmit/receive switch may be configured to switch between a transmit phase and a receive phase of an ultrasound scan. The transmit/receive switch may provide a receive signal communicated from an ultrasound transducer to a low noise amplifier when in the receive phase. An impedance of the transmit/receive switch may be dynamically adjusted by changing a resistance of the transmit/receive switch while the transmit/receive switch is in the receive phase. The low noise amplifier may be configured to amplify the receive signal. In various embodiments, a gain of the low noise amplifier is independent of the resistance of the transmit/receive switch.
