How to Calculate Input Capacitance in High-Frequency Gain of CE Amplifier?
Input Capacitance in High-Frequency Gain of CE Amplifier calculator uses Input Capacitance = Collector Base Junction Capacitance+Base Emitter Capacitance*(1+(Transconductance*Load Resistance)) to calculate the Input Capacitance, The Input capacitance in high-frequency gain of CE amplifier formula is defined as equal to Cbe. (Well, in practice there is small parasitic capacitance between collector and emitter) Common collector circuit has collector end grounded (Vcc is ground for AC), so input capacitance equals base-collector capacitance provided load has no capacitance of its own. Input Capacitance is denoted by Ci symbol.
How to calculate Input Capacitance in High-Frequency Gain of CE Amplifier using this online calculator? To use this online calculator for Input Capacitance in High-Frequency Gain of CE Amplifier, enter Collector Base Junction Capacitance (Ccb), Base Emitter Capacitance (Cbe), Transconductance (gm) & Load Resistance (RL) and hit the calculate button. Here is how the Input Capacitance in High-Frequency Gain of CE Amplifier calculation can be explained with given input values -> 5.2E+8 = 0.0003+2.7E-05*(1+(0.0048*1490)).
