MDAC for Pipeline ADC - Timing Analysis

[Puppet123]

Hello,

I am examing this MDAC for a Pipeline ADC and am confused about the style of the notation on the schematic in terms of the switches.

What do they mean ?

The switches say VDD/GND and P2D and P1D.

Does that mean set that point to VDD at P2D and GND at P1D ?

How would I do this if I am correct ?

Thank you.

The notation isn't commonly understood and needs explanation. I'm sure it becomes obvious if you read the paper where you copied the schematic more thoroughly.

How about this one ?

Is the "gnd" symbol mean apply vcm there ?
