In a Common Emitter (CE) BJT amplifier, which of the following options is correct?
1
The CE amplifier has the lowest input impedance among all the configurations.
2
Its input impedance is lower than CB configuration but higher than CC configuration.
3
The input characteristics are plotted between the input current (IB) and input voltage (VBE) at a constant IC.
4
If the magnitude of the output voltage increases, the input current decreases.
