## Output voltage of the common-base amplifier Solution

STEP 0: Pre-Calculation Summary
Formula Used
Vo = -(β*Ie*(1/Rc+1/Rl))
This formula uses 4 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.
Emitter current - Emitter current is the amplified output current of a bipolar junction transistor. (Measured in Ampere)
Load Resistance - Load resistance is the cumulative resistance of a circuit, as seen by the voltage, current, or power source driving that circuit. (Measured in Ohm)
Load resistance - Load resistance is the resistance value of load given for the network (Measured in Kilohm)
STEP 1: Convert Input(s) to Base Unit
