An experiment. Common base can amplify voltage if the output impedance is higher than the input impedance. Common Collector then replicates the voltage at a higher current.
Gain:
27.1db @ 10Mhz
7.7db @ 100Mhz
Parasitic capacitance interferes with the common collector stage, if I'm not mistaken. As evidence, a base resistor for it reduces its output (and thus total gain) even though it increases the gain of the common base stage.
