Ic = Is * (exp(VBE/Vt) - 1)

Substituting typical values:

where Vtn is the threshold voltage at zero body bias, γ is the body effect coefficient, φf is the Fermi potential, and Vsb is the source-body voltage. Advanced Semiconductor Fundamentals Solution Manual

μn ≈ 1350 cm^2/Vs μp ≈ 480 cm^2/Vs

3.1 Analyze the current-voltage characteristics of a BJT. Ic = Is * (exp(VBE/Vt) - 1) Substituting

Vbi = (kT/q) * ln(Na * Nd / ni^2)

The current-voltage characteristics of a BJT can be described by the Ebers-Moll model. The collector current can be expressed as: γ is the body effect coefficient

Vth = Vtn + γ * (√(2φf + Vsb) - √(2φf))

The built-in potential barrier in a pn junction can be calculated using the following equation:
