Circuits, devices and methods generating an ultrasound pulse are provided herein. An ultrasound probe includes an array of transducer elements configured to transmit an ultrasound signal toward a target structure in a region of interest, and an array of pulse generators for driving a respective transducer element. Each of the pulse generators are coupled to a respective transducer element and include a driver circuit configured to receive a control signal and to output a driving signal, a switching element coupled to the driver circuit, and a resonant circuit coupled to the switching element and the respective transducer element, wherein the resonant circuit is configured to provide a transmit pulse to the respective transducer element based on the driving signal. The switching element may comprise a gallium nitride field effect transistor (GaN FET).
