Abstract: In an embodiment, an electronic circuit includes: an input differential pair including first and second transistors; a first pair of transistors in emitter-follower configuration including third and fourth transistors, and an output differential pair including fifth and sixth transistors. The third transistor has a control terminal coupled to the first transistor, and a current path coupled to a first output terminal. The fourth transistor has a control terminal coupled to the second transistor, and a current path coupled to a second output terminal. The fifth transistor has a control terminal coupled to the first transistor, and a first current path terminal coupled to the first output terminal. The sixth transistor has a control terminal coupled to the second transistor, and a first current path terminal coupled to the second output terminal. First and second termination resistors are coupled between the first pair of transistors and the output differential pair.
