Push-Pull Follower
If we put two emitter followers together (npn transistor for positive
voltages; pnp transistor for negative voltages), we get a push-pull
follower.
If > 0.7V, then the current is amplified by the npn transistor.
If < -0.7V, then the current is amplified by the pnp transistor.
Beware that there is a “dead band” when Vin is between 0.7V
