Best Answer

In any transistor circuit , there is a phase shift. It takes a finite time for the controlling signal, usually on the base connection, to have an effect on the circuit and cause a change to the output. The shape of the signal remains but it is shifted in time (phase). The difference varies by configuration. It can be as much as180 degrees if the circuit is inverting the signal. The addition of passive components add to the shift.

What is the phase relationship between the input and output signals of the common collector amplifier?

Common emitter is the only transistor configuration that has an 180 degree phase difference between input and output. Common base and common collector outputs are in phase with the input.***********************************That is incorrect.The output of the common emitter is inverted, there is no phase shift.


Why phase shift of ce configuration is 180 out of phase while cc has same phase?

In a ce amplifier, an increase of base voltage causes the collector current to rise. This causes an increased voltage drop through the collector load resistor, so the collector voltage drops. With a cc amplifier the increase in current causes more voltage across the emitter load resistor, therefore the emitter voltage rises.


Which transistor configuration has the highest voltage gain?

Common Emitter(CE) Configuration possess largest voltage gain among the three(CE CB CC).


Why common emitter configuration is mostly used for transistor as switch?

because in ce configuration value of input voltage requried to make the transistor on is very less value of the output voltage or output current

How output voltage is out of phase in CE?

It should be ~180 degrees out of phase, because a CE amplifier is an inverter. A BJT CE amplifier is a good example to look at. The output is across CE, and at a minimum total output voltage is split across CE and some resistor R. As a higher voltage is applied to the base, the current flow through CE increases as a result of the resistance of CE decreasing. This boils down to a simple voltage divider at the output, Vout = CE / (R + CE). As CE decreases as a result of the input increasing, Vout will decrease.


Do you have 180 phase shift in voltage in ce mode even if you use pnp?

Common Emitter (CE) mode, or Class A operation, always introduces a 180 degree phase shift, i.e. it is inverting, whether or not you use PNP or NPN transistors.In NPN, an increase in base voltage increases the collector current, which decreases the collector voltage.In PNP, a decrease in base voltage increases the collector current, which increases the collector voltage.They are both inverting.When I say "increase" or "decrease" of voltage, I mean that "increase" means "towards the plus power supply".


What is Saturation voltage of bjt?

It is the CE (collector - emitter) voltage at a given collector current when the transistor is fully on. Increasing the base current will not lower the CE voltage any more once saturation has been reached.
