I am trying to calculate the switching power needed when moving between different switching positions in a capacitive DAC. The image below depicts the energy needed to go from a certain position to another for a conventional capacitive switching DAC. For example, in going from state A to B the paper claims a total of CVref^2 is required to be drawn from the reference generator. However what I found is only half this value. What is wrong with my calculation?
