Cut-off Frequency Solution

STEP 0: Pre-Calculation Summary

Formula Used

Cut-off Frequency = Saturated Drift Velocity/(4*pi*Gate Length)
f_co = V_s/(4*pi*L_gate)
This formula uses 1 Constants, 3 Variables

Constants Used

pi - Archimedes' constant Value Taken As 3.14159265358979323846264338327950288

Variables Used

Cut-off Frequency - (Measured in Hertz) - Cut-off Frequency is defined as corner frequency is a boundary in system's frequency response at which energy flowing through system begins to be reduced rather than passing through.
Saturated Drift Velocity - (Measured in Meter per Second) - Saturated Drift Velocity is the maximum velocity that can travel in a charge carrier of a semiconductor.
Gate Length - (Measured in Meter) - Gate Length is defined the distance between the source and the drain electrodes along the direction perpendicular to the plane of the semiconductor material, and parallel to the gate electrode.

STEP 1: Convert Input(s) to Base Unit

Saturated Drift Velocity: 5 Millimeter per Second --> 0.005 Meter per Second (Check conversion here)
Gate Length: 13.24 Micrometer --> 1.324E-05 Meter (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

f_co = V_s/(4*pi*L_gate) --> 0.005/(4*pi*1.324E-05)

Evaluating ... ...

FAQ

What is Cut-off Frequency?

The Cut-off frequency MESFET formula is defined as a cutoff frequency, corner frequency, or break frequency is a boundary in a system's frequency response at which energy flowing through the system begins to be reduced rather than passing through and is represented as f_co = V_s/(4*pi*L_gate) or Cut-off Frequency = Saturated Drift Velocity/(4*pi*Gate Length). Saturated Drift Velocity is the maximum velocity that can travel in a charge carrier of a semiconductor & Gate Length is defined the distance between the source and the drain electrodes along the direction perpendicular to the plane of the semiconductor material, and parallel to the gate electrode.

How to calculate Cut-off Frequency?

The Cut-off frequency MESFET formula is defined as a cutoff frequency, corner frequency, or break frequency is a boundary in a system's frequency response at which energy flowing through the system begins to be reduced rather than passing through is calculated using Cut-off Frequency = Saturated Drift Velocity/(4*pi*Gate Length). To calculate Cut-off Frequency, you need Saturated Drift Velocity (V_s) & Gate Length (L_gate). With our tool, you need to enter the respective value for Saturated Drift Velocity & Gate Length and hit the calculate button. You can also select the units (if any) for Input(s) and the Output as well.
