Ultrasound front-end circuit combining the transmitter and automatic transmit/receiver switch

An ultrasound receiving and transmitting circuit, comprising:

• a transmit pulser configured to provide transmit pulses to an ultrasound transducer;
• a receiver configured to receive pulses from said ultrasound transducer;
• and
• a switching circuit including first and second transform coils configured to alternatively couple and decouple said transmit pulser and said receiver to said ultrasonic transducer, whereby said first transformer coil being coupled with said transmit pulser and said second transformer coil being coupled with said ultrasound transducer.

A method for providing ultrasound signals, comprising:

• providing transmit pulses to an ultrasound transducer;
• receiving pulses from said ultrasound transducer;
• and
• alternatively coupling and decoupling said transmit pulses and said receive pulses to set ultrasound transducer, said alternatively coupling employing first transformer coils and second transform coils disposed on a common transformer core, whereby said first transformer coil being coupled with a transmit pulser for providing said transmit pulses and said second transformer coil being coupled with said ultrasound transducer.
