DEFINITION

Classification: 327/575

Darlington connection:

(under subclass 574) Subject matter wherein a nonlinear circuit includes a connection of two similar transistors where their collectors are tied together and the emitter of the first transistor is directly coupled to the base of the second transistor and the emitter current of the first transistor equals the base current of the second transistor.

(1) Note. A Darlington connection is also called a Darlington pair, double emitter-follower or beta-multiplier.
