Amplification is process through which weak input signal is amplified. Common Base BJT Amplifier. The purpose of biasing is to es-tablish a Q-point about which variations in current and voltage can occur in response to an ac input signal. Re is actually two resistors in series one of which will be call Rg and is called the gain resistor since it controls the voltage gain or amplification.
Lecture 12-2 BJT Circuit Analysis SPICE solves the system of nonlinear equations to obtain the voltages and currents Is this circuit in the active region.
