Formula Used

Gate Length = DC Transient Time*Saturation Drift Velocity
L_g = T_o*V_ds
This formula uses 3 Variables

Variables Used

Gate Length - (Measured in Meter) - Gate Length is an important parameter as it determines the size of the gate region and hence affects the device's electrical characteristics.
DC Transient Time - (Measured in Second) - DC Transient Time refers to the time taken by an electron to travel from the cathode to the anode of an electron device and then back to the cathode.
Saturation Drift Velocity - (Measured in Meter per Second) - Saturation Drift Velocity refers to the maximum velocity that an electron or hole can attain in a given material when subjected to an electric field.

STEP 1: Convert Input(s) to Base Unit

DC Transient Time: 0.16 Second --> 0.16 Second No Conversion Required

Round Trip DC Transit Time

Go DC Transient Time = (2*[Mass-e]*Drift Space Length*Electron Uniform Velocity)/([Charge-e]*(Repeller Voltage+Beam Voltage))

DC Voltage

Go DC Voltage = (0.5*[Mass-e]*Electron Uniform Velocity^2)/[Charge-e]

Reflection Coefficient

Go Reflection Coefficient = (Voltage Standing Wave Ratio-1)/(Voltage Standing Wave Ratio+1)

Insertion Loss

Go Insertion Loss = 20*log10(Voltage/Input Signal Amplitude)

Pitch Angle

Go Pitch Angle = arsin(Phase Velocity/[c])

Phase Velocity

Go Phase Velocity = [c]*sin(Pitch Angle)

Voltage Standing Wave Ratio

Go Voltage Standing Wave Ratio = Maximum Voltage/Minimum Voltage

Ratio of Voltage Wave

Go Voltage Standing Wave Ratio = sqrt(Power Standing Wave Ratio)
