Final answer:
To develop a linear delay model for a 3-input NOR gate driving four 2-unit inverters, we can calculate the parameters such as logical effort, electrical effort, parasitic delay, and total delay.
Step-by-step explanation:
To develop a linear delay model for a 3-input NOR gate driving four 2-unit inverters, we can calculate the parameters as follows:
(a) Logical effort g: The logical effort is the ratio of the input capacitance to the output capacitance. In this case, there are three inputs to the NOR gate, so the logical effort is 3.
(b) Electrical effort (fanout) h: The electrical effort is the ratio of the output capacitance to the input capacitance. Since there are four inverters connected to the output of the NOR gate, the electrical effort is 4.
(c) Parasitic delay p: The parasitic delay is the delay introduced by the capacitances and resistances in the gate. Without specific values for the capacitances and resistances, we cannot calculate the parasitic delay.
(d) Delay d: The delay of the gate is the sum of the logical effort and the electrical effort. In this case, the delay is 7 (3 + 4).
