I am very very new to the electronic engineering side of things but I am taking a class on Computer Architecture. I have ran into a problem.
Power = Capacitive Load * Voltage ^ 2 * Frequency Switched.
I have a hard time understanding what capacitive load is. Let's say I have a CPU with the following specs.
Uses 3.3 Volts
Requires 29.1 Watts
Has a clock rate of 200 Mhz
How would I use these three bits of info to find a capacitive load? Can I? I'm not sure if I am going about this correctly. Help is appreciated! :)
Answer
This is a simple arranging to resolve the equation for Capacitive load. Like so
\$ \frac{Power}{Voltage^2 \times frequency} = Capacitive Load \$
With the numbers you gave we get:
\$ \frac{29.1}{3.3^2 \times 200*10^6} = 1.33\times 10^{-8} \mathrm{F} \$
F is farads the unit for capacitance.
I have assumed that the given equation takes power to be in watts.
