How do Mc9 and Mc10 act as negative miller capacitance as mentioned in Figure 4.2 of http://lib.tkk.fi/Dipl/2011/urn100433.pdf

They act as capacitors, and are cross coupled across a differential amplifier. So the voltage they see is the opposite sign as normal.

For slide number 7 of https://ocw.mit.edu/courses/electrical-engineering-and-computer-science/6-976-high-speed-communication-circuits-and-systems-spring-2003/lecture-notes/lec6.pdf , why If CN too high, input impedance has inductive component ? How do I apply miller multiplication theorem as in slide number 4 of https://view.officeapps.live.com/op/view.aspx?src=http%3A%2F%2Fcourses.ece.msstate.edu%2FECE3424%2Fpptx%2FCh12_Parasitics%2FCh12-4_HighFreq.pptx to understand the inductive component ?
