Abstract
An ultrasound transceiver that overcomes many of the deficiencies of conventional ultrasound transceivers by providing the ability to transmit high power and high frequency arbitrary waveforms with low distortion and with the ability to monitor the transmit signals through the receiver during the transmit period, the transceiver circuit having a transducer element to emit an ultrasound signal and to receive a reflected ultrasound signal, a transformer circuit having a transformer with a secondary winding coupled to the transducer element and a primary winding, an H-Bridge transmit waveform circuit coupled to the primary winding of the transformer to generate a transmit waveform signal to the transducer element via the transformer, an FET clamp coupled to the secondary winding of the transformer, and a receiver circuit having an input coupled to the FET clamp.
