Bjt is used as an amplifier only when
WebA number of single-stage amplifiers are cascaded to form a Multi-stage amplifier. Let us see how a single-stage amplifier is built, which is the basic for a Multi-stage amplifier. Single-stage Transistor Amplifier. When only one transistor with associated circuitry is used for amplifying a weak signal, the circuit is known as single-stage ... WebMay 4, 2024 · 14. "Reinforced diode". Diode connected BJT aka "active diode" is simply a transistor which collector is connected to the base. Thus the collector-emitter part of the transistor is connected in parallel to its base-emitter junction so we can think of this combination as of a "reinforced diode". The current through this "composed diode" is …
