The following is the summary of my work in the week of Feb 13 - Feb 20. 

	1. Read papers about hysteretic DC/DC converters which uses 
	the output voltage ripple to directly control the input waveform   
	of the power transistors. This technique may be used to reduce
	the output voltage ripple of the PWM converter suffering from  
	a big output voltage ripple in the feedback loop. 

	2. Modifying the DAC DC/DC converter design to fit into the 
	multi-phase PFM design. 
	
	3. Finished the poster for SRC review and graduation.
