the common-collector configuration gives the benefits of a high input resistance, low output resistance, and a high current gain. The combination of high input resistance and low output resistance allows a common-collector amplifier to function as a buffer that keeps loading effects low if the cir...
Q4. The BJT in the common-base (CB) amplifier in Figure 4 has Figure 4 B =100, VBE = 0.7 V. +12 V ξ5 ΚΩ HCC? in the active mode. The coupling capacitors are very large. The output resistance r of the transistor can be neglecte...
An amplifier includes a first pair of transistors (the first pair) that defines a first output, each transistor of the first pair having a gate coupled to a first input terminal; a second pair of transistors (the second pair) that defines a second output, each transistor of the second ...
This calculator computes the Diffusion Resistance (rp), Transconductance (gm) and Output Voltage gain (AV) for a common emitter (CE) BJT amplifier. In the common emitter mode the base terminal of the transistor is the input, the collector is the output and the emitter is common to both the...

The common-base amplifier has a very low input resistance, which is equal to the incremental emitter resistance re. This is the same as the output resistance of the emitter-follower amplifier that has a low equivalent resistance on its base, which makes sense since we are looking into the em...
Hint: In a common emitter amplifier, when base voltage increases, base current increases. It also causes an increase in the collector current which in turn causes a voltage drop in the collector resistor. Because the output is situated below the collector resistance. ...
Base current is then increased, which ends up in the increasing of the collector current. The output voltage of the amplifier before the decoupling cap equals to Vcc-Ic*Rc. (Vcc is the supply voltage of the collector;Ic is the collector current, Rc is the collector resistor). ...
The transmission line is terminated at both ends in its characteristic impedance by a termination resistor approximately equal to such characteristic impedance connected in series with the emitter to base junction resistance of a termination transistor connected as a common base amplifier. A signal ...
