Hello all,

I have problem regarding the calculation of the gate capacitance of any logic gate
how do i calculate it.

Regards
 

Gate capacitance = Cox * W * L
where,
W is the width of the transistor
L is the length of the transistor
Cox is the capacitance denisty of the gate (in F/m²)

Then u can multiply the final value with the total number of gates ur path see
 

Hello Eng_semi,

I have a doubt that whether ,i have to multiply or add the capacitance of the individual gate as the path see, because the substrate of the NMOS is at Ground and Substrate of my PMOS is Vdd.

can u give the example of Nand and Domino Logic.

Regards,
Preet
