Hy, I am doing final semester M.E in VLSI. I am going to do my PhD full time in Analog VLSI domain. Can anyone guide me how to choose a research work under Analog VLSI or the categories under analog VLSI. Thanks in advance.

If you can, do your study on ADC/DAC subject.They are future of the analog world because everything goes digital nowadays and the sole interfaces will be ADC/DAC between analog nature and digital.
