A diode meets that requirement. It is the simplest form of active device unless you want to consider air as an active device in a spark gap circuit =)An active device is any type of circuit component with the ability to electrically control electron flow
A Device is said to be active if...
(i) It is a source of Power in the circuit...
(ii) It amplifies any voltage or current in a circuit...
(iii) It acts as a switch ie., has modes equivalent to ON and OFF...
