Transistor Aspect Ratio Solution

STEP 0: Pre-Calculation Summary

Formula Used

Aspect Ratio = Width of Channel/Channel Length
WL = b_ch/L_ch
This formula uses 3 Variables

Variables Used

Aspect Ratio - Aspect Ratio is the ratio of the width of the channel to the length of the channel.
Width of Channel - (Measured in Meter) - Width of Channel is the dimension of the channel of MOSFET.
Channel Length - (Measured in Meter) - The Channel Length, L, which is the distance between the two n-p junctions.

STEP 1: Convert Input(s) to Base Unit

Width of Channel: 10.2 Micrometer --> 1.02E-05 Meter (Check conversion here)
Channel Length: 2.15 Micrometer --> 2.15E-06 Meter (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

WL = b_ch/L_ch --> 1.02E-05/2.15E-06

Evaluating ... ...

WL = 4.74418604651163

STEP 3: Convert Result to Output's Unit

4.74418604651163 --> No Conversion Required

FINAL ANSWER

4.74418604651163 ≈ 4.744186 <-- Aspect Ratio

What is the significance of aspect ratio?

Aspect ratio calculations are generally important while cropping and editing images or videos. The right aspect ratio can ensure that the final product does not appear to be 'stretched out' or has important elements cropped out. The aspect ratio is equally important as the benefit and content from the projector.

What is the perfect aspect ratio?

Research into the history of aspect ratios indicates that the 1.78:1 aspect ratio was adopted by the standards committee of the Society of Motion Picture Engineers in 1930. It also indicates that the factors that may have led to widescreen motion picture systems may no longer be applicable.

How to Calculate Transistor Aspect Ratio?

Transistor Aspect Ratio calculator uses Aspect Ratio = Width of Channel/Channel Length to calculate the Aspect Ratio, Transistor aspect ratio is the ratio of the .width of the channel to the length of the channel.So for a given gate-source voltage, a higher W/L ratio results in a higher current. Aspect Ratio is denoted by WL symbol.

How to calculate Transistor Aspect Ratio using this online calculator? To use this online calculator for Transistor Aspect Ratio, enter Width of Channel (b_ch) & Channel Length (L_ch) and hit the calculate button. Here is how the Transistor Aspect Ratio calculation can be explained with given input values -> 4.744186 = 1.02E-05/2.15E-06.

FAQ

What is Transistor Aspect Ratio?

Transistor aspect ratio is the ratio of the .width of the channel to the length of the channel.So for a given gate-source voltage, a higher W/L ratio results in a higher current and is represented as WL = b_ch/L_ch or Aspect Ratio = Width of Channel/Channel Length. Width of Channel is the dimension of the channel of MOSFET & The Channel Length, L, which is the distance between the two n-p junctions.

How to calculate Transistor Aspect Ratio?

Transistor aspect ratio is the ratio of the .width of the channel to the length of the channel.So for a given gate-source voltage, a higher W/L ratio results in a higher current is calculated using Aspect Ratio = Width of Channel/Channel Length. To calculate Transistor Aspect Ratio, you need Width of Channel (b_ch) & Channel Length (L_ch). With our tool, you need to enter the respective value for Width of Channel & Channel Length and hit the calculate button. You can also select the units (if any) for Input(s) and the Output as well.
