Correct option is A) A transistor is used as an amplifier in common-emitter (CE) configuration. In this configuration, base-emitter junction is forward biased and collector-base junction ... WebJan 2, 2024 · A “Class A Amplifier” operation is one where the transistors Base terminal is biased in such a way as to forward bias the Base-emitter junction. The result is that the transistor is always operating halfway between its cut-off and saturation regions, thereby allowing the transistor amplifier to accurately reproduce the positive and negative ...
WebMar 17, 2024 · Common-base amplifiers use the base as the common terminal for an ac signal and capacitively couple the input signal to the emitter. The common-base output … In electronics, a common collector amplifier (also known as an emitter follower) is one of three basic single-stage bipolar junction transistor (BJT) amplifier topologies, typically used as a voltage buffer. In this circuit the base terminal of the transistor serves as the input, the emitter is the output, and the collector is common to both (for example, it may be tied to ground reference or a power suppl…
