- 1Due to the Early effect, if the magnitude of the output collector-emitter voltage increases, the base-emitter input voltage required for a constant base current shifts, making input current decrease for a fixed input voltage.✓
- 2The input characteristics are plotted between the input current (IB) and input voltage (VBE) at a constant IC.
- 3Its input impedance is lower than the CB configuration but higher than the CC configuration.
- 4The CE amplifier has the lowest input impedance among all configurations.
Correct answer
Due to the Early effect, if the magnitude of the output collector-emitter voltage increases, the base-emitter input voltage required for a constant base current shifts, making input current decrease for a fixed input voltage.
