Fanout of Gate Solution

STEP 0: Pre-Calculation Summary

Formula Used

Fanout = Stage Effort/Logical Effort
h = f/g
This formula uses 3 Variables

Variables Used

Fanout - Fanout is the number of similar gate inputs that a gate output can drive. In other words, it represents the number of gates or loads connected to the output of the current gate.
Stage Effort - Stage effort is a measure of how much effort (or delay) is required to drive the output of a logic gate or circuit to the next stage in the design.
Logical Effort - Logical effort is a metric that represents the intrinsic speed of a logic gate.

STEP 1: Convert Input(s) to Base Unit

Stage Effort: 3.99 --> No Conversion Required
Logical Effort: 4.76 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

h = f/g --> 3.99/4.76

Evaluating ... ...

h = 0.838235294117647

STEP 3: Convert Result to Output's Unit

0.838235294117647 --> No Conversion Required

FINAL ANSWER

0.838235294117647 ≈ 0.838235 <-- Fanout

Capacitance of External Load

Go Capacitance of External Load = Fanout*Input Capacitance

Fanout of Gate

Go Fanout = Stage Effort/Logical Effort

Stage Effort

Go Stage Effort = Fanout*Logical Effort

Gate Delay

Go Gate Delay = 2^(N Bit SRAM)

Fanout of Gate Formula

Fanout = Stage Effort/Logical Effort
h = f/g

What is stage effort?

Stage effort is a measure of the effort required to drive the load capacitance of the next stage in a CMOS circuit. It takes into account the intrinsic delay of the gate and the load capacitance it drives.
