AUDIO OUTPUT STAGE - radioremembered.org

The outputor sometimes called the power-amplifierstage follows the detector, and is the last stage in the signal path of the receiver. The signal level from the preceding detector stage would be about sufficient to operate a pair of …
Amplifiers: Output stage - Lenard Audio
https://education.lenardaudio.com/en/12_amps_5.html
Darlington complementary is the basic order in how the output stage of an amplifier is taught. All output transistors are arranged as emitter followers. The collectors are connected directly to the rails. The emitter follows the signal on base within 650mV. The output transistors do not increase the size of the audio signal. Output transistors can only add …
AM Pocket Radio -- Audio Output Stage
https://www.petervis.com/Radios/am-pocket-radio-solid-state/am-pocket-radio-audio-output.html
The audio output stage of an early pocket radio usually consisted of a pair of audio transformers, which you might remember seeing in the photographs in the previous pages of this multi-page article. Here is a circuit diagram extract of a typical class A push-pull design found in vintage radios. Back then, only PNP transistors were readily available and therefore all the transistors …

Linear Audio is a book-format audio magazine published half-yearly by Jan Didden. Introduction These articles introduce a systematic approach to the design of very low distortion push-pull output stage for audio power amplifiers. Work on this has been going on (well, on and off, to tell the truth) since February 2 nd, 1981, according to my ...

Output Stage 1. Deliver large amounts of current into RL without self destructing. 2. Provide a high input impedance at the base of Q4, Q5. 3. Minimize distortion when transitioning between positive and negative output currents.

The output stage is a triplet Darlington, as recommended by Cordell, whose suggested output and driver devices are also used here [5]. By the way, when using such compound devices, always return the bleed resistors to the top of the emitter resistors, or cross-connect them to the other stage.

Output Stage Protection None of my amplifier designs include anything more than a supply line fuse to limit damage from overload and shorted outputs. Speaker protection in the form of an output coupling capacitor is included in all my recent designs, and even in the event of capacitor failure the overall feedback still limits the maximum ...

The role of an output stage is to provide power gain. It should have high input impedance and low output impedance. An obvious choice for this stage is the emitter follower. However, in order to provide both current sourcing and sinking capabilities, two complementary followers are needed, an NPN type to source and a PNP type to sink current.
