dc.description.abstract	this thesis proposes an mri-compatible integrated cmos ampli er that is capable of di- rectly driving an ultrasound transducer for hifu applications. the output stage of the integrated amplifier operates in class de mode with its output directly connected to a shunt capacitor and an ultrasound transducer without the need for an inductor. this design was simulated with spectre simulator using the 0:8 m 5/20 v cmos process data available from teledyne-dalsa semiconductor. the proposed integrated ampli er has an e ciency of 80% with 1 w of output power at 1 mhz and achieves an acceptable level of third harmonic. a layout of the integrated ampli er was prepared. the integrated ampli er occupies a die area of approximately 2:5 mm by 1:6 mm including input-output pads.	en_us
