[SOLVED] A question about "analog design essentials" book

[petelee]

Hi Analog expert,

I have a question regarding this material which is from the book "Analog design essentials". Below is the link we can find in the website if you search for "Miller CMOS OTA Springer" with google.

From page 18, there's a graph and there're "Cn1ct" and "Cn1~gm6" on the left side of the graph. Does anybody know about the meaning of them?

It would be great if you educate me.

Thanks,

i figured that "ct" might stand for "constant" and "~" mean "proportional".
