dc.description.abstractThis 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
