This thesis proposes to use current type DAC to replace the traditional unipolar and bipolar pulse generator. Using digital signal to control pulse generator can be effectively used in ultrasound scanning with variety mode, Using 200Mhz sampling frequency to control double 6-bit DAC with 128 current cell current type output with 100 ohm loading resistor to generates sine wave signal with 10MHz frequency and 40V pick voltage. Compared to conventional pulse generator , current type DAC have provide more diverse selection , make it easier to change signal amplitude and frequency, eliminating the adder and multiplier to make the system more compact , the characteristics of this work is that replaces the traditional logic circuit switch with current type logic gates MCML (Mos Current Mode Logic) using to enhance the reaction speed of the decoder that let the second harmonic distortion of the output sine wave can be pull to 39.9dbc, and reduce the process variation of current source by using staggered layout techniques .

Piezoelectric transducer is the most application method for ultrasonic sensor. Ultrasonic sensor is widely used in our life such as automobile parking sensor, water cleaning system, medical imaging…etc. However, the characteristics of piezoelectric materials will change with the environment variation, the process deviation, the damage of the material…etc. Thus, the proper operation point for an ultrasonic transducer will be different from time to time and from the other transducers. In this thesis, equivalent circuit and the operation of the ultrasonic transducer is investigated in detail. With discuss, the most efficiency frequency will be known. Besides, a circuit can trace the proper operating frequency for an ultrasonic transducer by phase controlling, and driving ultrasonic transducer, is proposed in this thesis. Finally, the calibration circuit is implemented and verified by ultrasonic transducer which have different operating frequency. Experiment results show that ultrasonic transducers can drive at the most efficiency frequency with inaccuracy error less than 0.15%.

This thesis utilizes the relay feedback approach to designing a resonance- tracking driver for ultrasonic transducers of different frequencies ranging from 20 kHz to 60 kHz. The driver connected with the transducer in a feedback loop constitutes a relay feedback system, which automatically oscillates and generates sinusoidal driving voltage right at the targeted resonant frequency of the transducer, thereby achieving better transducer efficiency. The driver mainly consists of an FPGA and a class-D power amplifier. The contribution of this thesis is to design the algorithms on the FPGA. The algorithms include a tunable bandpass filter, a tunable delay, and an optimal pulse width modulator, which together make the relay feedback driver more intelligent and more precise.

The Current research relates to ultrasound probes, which according to their application use different frequencies. In general, driving an ultrasound probe must find a suitable way to manually adjust the operating frequency of the probe, but it’s not convenient and accurate. However, in a suitable operating frequency, its power will become higher. Therefore, in this study, we designed a system that can adjust to a suitable and accurate operating frequency automatically. In this study, we developed a function generator using an AD5930 which can produce continuous or burst waveforms. The use of burst waveforms can prevent damage caused by overheat. The output signal is then fed to the inverter to adjust the signal amplitude according to the power supply voltage and drive the ultrasound transducer. A C++ produced software was used to upload parameters to an Arduino UNO microcontroller board so that it can program the AD5930 burst waveform generator to adjust the parameters of the output signal such as the frequency and the burst time. Using this hardware and software concept applied on different ultrasound transducers, we expect to expand the application of ultrasound transducers in the biomedical field. An Arduino microcontroller combined with the AD5930 circuit produces output digital and/or analog signals with stable frequency. The user can easily and conveniently adjust to a desired fixed output frequency or set an increasing sweep frequency. This type of device could be used in various ultrasonic probe applications.
