Gate to Base Capacitance Solution

Follow our step by step solution on how to calculate Gate to Base Capacitance?

FIRST Step Consider the formula

C gb = C g - (C gs + C gd)

Next Step Substitute values of Variables

∴

C gb = 59.61μF - (14.61μF + 10μF)

Next Step Convert Units

∴

C gb = 6E-5F - (1.5E-5F + 1E-5F)

Next Step Prepare to Evaluate

∴

C gb = 6E-5 - (1.5E-5 + 1E-5)

Next Step Evaluate

∴

C gb = 3.5E-05F

LAST Step Convert to Output's Unit

∴

C gb = 35μF
