%X A design of a gradient waveform generator with self-triggering function for magnetic resonance imaging(MRI) is proposed.In the present design,a high precision DAC(24-bit) chip having a relatively large group delay is used.With this design and the proposed self-triggering technique,the group delay of gradient waveforms can be eliminated.As a result,high precision DAC can be applied to MRI scanner.
