Mark out all the correct statements about the distributed rc line.
A. ) Delay of a wire in the distributed rc line is a quadratic function of its length
B. ) Delay of the distributed rc line is one half of the delay that would have been predicted by the lumped RC model
C. ) rc delays should only be considered when tp,rc >> tp,gate of the driving gate
D. ) rc delays should only be considered when the rise (fall) time at the line input is smaller than RC, R and C are lumped resistance and capacitance of the wire respectively

Silicide can be used to reduce the sheet resistance of polysilicon.
A. ) True
B. ) False
To minimize the resistance of the wires, it is desirable to keep the cross section (W x H) of the wire as large as possible with device dimensions scaling down.
A. ) True
B. ) False
