  • Analog beamformers for continuous wave ultrasonic receivers
    Patent number: 7502278
    Abstract: Analog beamformers for continuous wave ultrasonic receivers, typically realized in integrated circuit form and using a direct quadrature baseband conversion architecture for CW Doppler to eliminate a second down conversion mixer and second synthesizer. The beamformers use integrated mixers and LO's for phase steering, and dedicated ring counters for each channel for lower noise. Input filtering may be provided with switchable RF input low pass filters. The integrated circuit includes the ultrasound signal VGA and beamformer on the same chip. An auxiliary channel may be included for a self-test mode. Also a programmable bit soft shutdown feature, programmable via the serial port, allows disabling individual channels. Various other features are disclosed including cascading of multiple integrated circuits for a much greater number of channels.
