Base Junction Width of Amplifier

Go Base Junction Width = (Base Emitter Area*[Charge-e]*Electron Diffusivity*Thermal Equilibrium Concentration)/Saturation Current

Differential Voltage in Amplifier

Go Differential Input Signal = Output Voltage/((Resistance 4/Resistance 3)*(1+(Resistance 2)/Resistance 1))

Current Gain of Amplifier

Go Current Gain = Output Current/Input Current

Power Gain of Amplifier

Go Power Gain = Load Power/Input Power

Current Gain of Amplifier in Decibels Formula

Current Gain in Decibels = 20*(log10(Current Gain))
A_i(dB) = 20*(log10(A_i))

Why do we calculate current gain in decibels?

Current gain is measured in dB for high voltage assets because for very high voltage values it is very tough to measure it practically. The decibel scale is logarithmic which compresses larger values on a smaller scale.
