How to Calculate Collector-Base Capacitance?
Collector-Base Capacitance calculator uses Collector Base Capacitance = Emitter Base Junction Area*sqrt((Charge*Permittivity*Doping Density)/(2*(Built In Potential+Reverse Bias Junction))) to calculate the Collector Base Capacitance, The Collector-Base Capacitance formula is defined in a bipolar junction transistor (BJT) refers to the capacitance between the collector and the base terminals of the transistor. This capacitance arises due to the depletion region and the charge storage within the transistor. Collector Base Capacitance is denoted by C_{cb} symbol.
How to calculate Collector-Base Capacitance using this online calculator? To use this online calculator for Collector-Base Capacitance, enter Emitter Base Junction Area (A), Charge (q), Permittivity (ε), Doping Density (N_{b}), Built In Potential (ψ_{o}) & Reverse Bias Junction (V_{rb}) and hit the calculate button. Here is how the Collector-Base Capacitance calculation can be explained with given input values -> 1.4E+8 = 0.000175*sqrt((0.005*71*26)/(2*(4.8+2.55))).
