## Overall voltage gain of the common-base amplifier Solution

STEP 0: Pre-Calculation Summary
Formula Used
overall_voltage_gain = Common emitter current gain*(Input resistance/(Input resistance+Signal Resistance))*((1/Total resistance in collector+1/Load resistance)/Emitter Resistance)
Gv = β*(Ri/(Ri+Rs))*((1/R+1/Rl)/re)
This formula uses 6 Variables
Variables Used
Common emitter current gain- Common emitter current gain is highly influenced by two factors: the width of the base region, W, and the relative dopings of the base region and the emitter region.
Input resistance - Input resistance is the resistance value of the voltage amplifier (Measured in Ohm)
Signal Resistance- Signal Resistance is the resistance which is fed with the signal voltage source vs to an Amplifier
Total resistance in collector - The total resistance in collector is the opposition offered to the current passing through the collector. (Measured in Ohm)
Load resistance - Load resistance is the resistance value of load given for the network (Measured in Kilohm)
Emitter Resistance - Emitter Resistance is a dynamic resistance of the emitter-base junction diode of a transistor. (Measured in Ohm)
