transistors used in cascade, giving high gain and high input impedance
an electronic circuit using two transistors with the collectors connected together and the emitter of the first directly coupled to the base of the second
a pair of transistors "piggybacked" on one another so that the emitter of one feeds current to the base of the other in common-collector form
Two directly coupled transistors in which the emitter of the first drives the base of the second.
An amplifier consisting of two bipolar junction transistors with their collectors connected together and the emitter of one connected to the base of the other. Circuit has an extremely high current gain and input impedance.
Two transistors, connected so that their collectors are tied together and the emitter of the first is tied to the base of the second.
