WebThis emitter follower has a pair of transistors in the Darlington configuration. In this arrangement, the emitter current of one transistor becomes the base current of the second. The Darlington configuration … WebAn emitter follower configuration is a key configuration of BJTs where the output voltage “follows” the input voltage with (near) unity gain. It is also known as a ‘common collector’ because the base is the input, the emitter is the output and the collector is common to the base and emitter. incendie a puyoo https://danielanoir.com
