Consider the following inverter chain:
G=81 Cg1 =
The load capacitance (CL) is 81 times bigger than
the capacitance of the first minimum sized
inverter (Cg1). The second inverter is made f
times bigger than the first one. Assume drain
diffusion capacitance is same as the gate
capacitance (i.e. y=1)
If you can add any number of inverters in series
and size them as you wish to minimize the
propagation delay from input to the load
capacitance, how many total inverters would be
optimal to have? (Note: how many total, not how
may additional inverters)
