Hi,

How to determine the capacitance of a logic block. eg; let's say i have 2 nand gates connected in a logic block, How will i estimate/determine the capacitance of that logic block manually? If anyone have idea of it and if possible provide it with figure.

hi


u can have a look at the book "digital integrated circuits" by rabaey , chandrakasan:

in chapter 6 they show how to estimate the capacitance of logice gates in terms of minimum sized inverters...
