Abstract: A circuit and method for predistorting an input pulse to a micro-machined ultrasonic transducer (MUT) compensates for non-linearities in the transducer, thus allowing the transducer to provide a compensated output pressure wave having a low second order harmonic transmit energy. In another aspect of the invention, the output power of a MUT may be controlled.
