Unlike many other simple amplifiers (e.g. Cascode Amp), this amplifier has no DC offset — notice how, with or without the AC source, the input voltage (BLUE) and output voltage (GREEN) both average 0 V.
Also unlike other simple amplifiers, the output voltage is not greater than the input. The current is the value that ends up amplified, resulting is greater power at the output than the input. (Recall: Power = Volts * Amps)
