QUESTION: 1

### Propogation time is directly proportional to

Solution:

Propogation time is directly proportional to square of the propogation distance (x2 ). It is the time taken by the signal to move from input port to output port.

QUESTION: 2

### The total resistance can be given as

Solution:

The total resistance can be given as the product of nrRs where r is the relative resistance per section in terms of Rs.

QUESTION: 3

### Total capacitance can be given as

Solution:

Total capacitance can be given as the product of nc(square Cg) where c is the relative capacitance per section in terms of square Cg.

QUESTION: 4

Overall delay is directly proportional to

Solution:

The overall delay is directly proportional to n2 , where n is the number of pass transistors in series.

QUESTION: 5

The number of pass transistors connected in series can be increased if

Solution:

The number of pass transistors connected in series can be increased by connecting buffer in between.

QUESTION: 6

Buffer is used because

Solution:

Buffer is used for long polysilicon runs because it increses the speed and reduces the sensitivity to noise.

QUESTION: 7

The overall delay is ______ to the relative resistance r

Solution:

The overall delay is directly proportional to the relative resistance r. Overall delay is given as product of n^2rcƮ.

QUESTION: 8

Small disturbances of noise

Solution:

Small disturbanes of noise switches the inverter stage between 0 and 1 or vice versa. It disturbs the normal operation or behaviour.

QUESTION: 9

The buffer speeds up the

Solution:

The buffer speeds up the rise time of propogated signal edge. A buffer is the combination of two inverters in which one output is fed to the other as the input.

QUESTION: 10

Overall delay increases as n

Solution:

Overall delay increases as n increases where n is the number of pass transistors connected in series.
