# Application Example: Steady-state and Small-signal analysis of NPN BJT

#1

Steady-state and small-signal analysis of an npn bipolar junction transistor. Learn to calculate the collector current amplification factor (beta), small-signal current gain, and unity-current-gain cutoff frequency (fT).

This example describes the simulation of a npn bipolar junction transistor (BJT). In the first part we will perform steady-state simulations to calculate the current-voltage characteristics and the current gain of the BJT. In the second part of this example we will perform a small-signal analysis to calculate the unity-current-gain cutoff frequency (fT) of the transistor.
