What is the operating point of a Class A common emitter amplifier?
Approximately halfway between saturation and cutoff✓Richtige Antwort
Approximately halfway between the emitter voltage and the base voltage
At a point where the bias resistor equals the load resistor
At a point where the load line intersects the zero bias current curve
Erklärung
Class A requires the device to conduct throughout the whole cycle, so the quiescent point is placed roughly midway between saturation and cutoff on the load line. That leaves equal room for the positive and negative signal excursions before either limit clips the waveform.
