IMPORTANT FORMULAE FROM SEMICONDUCTOR DEVICES
1. ni2 = nenh
2. IE =IB + IC
3. For common base, Input Resistance RI =(ΔVEB /ΔIE)VCB = CONST
Output Resistance RO =(ΔVCB /ΔIC)IE = CONST
4. For common emitter, Input Resistance RI =(ΔVBE /ΔIB)VCE = CONST
Output Resistance RO =(ΔVCE /ΔIC)IB = CONST
5. Current amplification factors of a transistor (α and β),
α = (ΔIC / ΔIE), VC = constant
β= (ΔIc / ΔIB), VC = constant
α = β / (1 + β)
β = α / (1 - α)
6. Voltage gain in common Base = α(R2/ R1)
7. Voltage gain in common Emitter = β (R2/ R1)
