How to Calculate Cut-off Frequency using Maximum Frequency?
Cut-off Frequency using Maximum Frequency calculator uses Cut-off Frequency = (2*Maximum Frequency of Oscillations)/(sqrt(Drain Resistance/(Source Resistance+Gate Metallization Resistance+Input Resistance))) to calculate the Cut-off Frequency, The Cut-off Frequency using Maximum Frequency formula is defined as the frequency at which the small-signal voltage gain of the device drops to 0.707 or -3 dB of its maximum value. Cut-off Frequency is denoted by f_{co} symbol.
How to calculate Cut-off Frequency using Maximum Frequency using this online calculator? To use this online calculator for Cut-off Frequency using Maximum Frequency, enter Maximum Frequency of Oscillations (f_{m}), Drain Resistance (R_{d}), Source Resistance (R_{s}), Gate Metallization Resistance (R_{g}) & Input Resistance (R_{i}) and hit the calculate button. Here is how the Cut-off Frequency using Maximum Frequency calculation can be explained with given input values -> 30.05347 = (2*65)/(sqrt(450/(5.75+2.8+15.5))).
