Webemitter-follower, and is also noncritical. For example, a high-gain Darlington device increased the open-loop gain by all of 3dB, and had even less effect on the closed-loop gain. The emitter-follower output does reduce the maximum positive output by 0.6V. So if we expect to work well with a 4V supply (a 9V battery at WebThe diamond buffer or diamond follower is a four-transistor, two-stage, push-pull, translinear emitter follower, or less commonly source follower, in which the input transistors are folded, or placed upside-down with respect to the output transistors.

"WebJun 21, 2024 · An emitter follower can only conduct current one way. But, if you put a NPN and PNP transistor pair of emitter followers in series, the NPN sources the current and the PNP sinks current. So, the load can have current driven both ways. This is how a complimentary pair audio amp output works. " - Pnp emitter follower
