How to Calculate Base Resistance?
Base Resistance calculator uses Base Resistance = Cut-off Frequency in BJT/(8*pi*Maximum Frequency of Oscillations^2*Collector Base Capacitance) to calculate the Base Resistance, The Base Resistance formula is defined as a base resistor that controls the amount of current entering the base junction of a bipolar junction transistor (BJT) to cause it to conduct in the saturation region. Base Resistance is denoted by Rb symbol.
How to calculate Base Resistance using this online calculator? To use this online calculator for Base Resistance, enter Cut-off Frequency in BJT (fco), Maximum Frequency of Oscillations (fm) & Collector Base Capacitance (Cc) and hit the calculate button. Here is how the Base Resistance calculation can be explained with given input values -> 0.983203 = 30/(8*pi*69^2*0.000255).
