# TRANSISTOR AMPLIFIER TUTORIAL

Transistor as an Amplifier - Tutorialspoint
Input ResistanceOutput ResistanceEffective Collector LoadCurrent GainVoltage GainPower GainAs the input circuit is forward biased, the input resistance will be low. The input resistance is the opposition offered by the base-emitter junction to the signal flow definition, it is the ratio of small change in base-emitter voltage (ΔVBE) to the resulting change in base current (ΔIB) at constant collector-emitter voltaget resistance, Ri=ΔVBEΔIBWhere Ri = input resistance, VBE = base-emitter voltage, and IB = base current.See more on tutorialspoint
Common Emitter Amplifier and Transistor Amplifiers
ExamplePurposeUseApplicationsOperationPropertiesComponentsAdvantagesFunctionOtherStructureIn the previous introduction to the amplifier tutorial, we saw that a family of curves known commonly as the Output Characteristic Curves, relate the transistors Collector Current (Ic), to its Collector Voltage (Vce) for different values of the transistors Base Current (Ib). The best possible position for this Q-point is as close to the center position of the load line as reasonably possible, thereby producing a Class A type amplifier operation, ie. Vce = See more on electronics-tutorials

Single-Stage Transistor AmplifierPractical Circuit of A Transistor AmplifierVarious Circuit CurrentsWhen only one transistor with associated circuitry is used for amplifying a weak signal, the circuit is known as single-stage amplifieryzing the working of a Single-stage amplifier circuit, makes us easy to understand the formation and working of Multi-stage amplifier circuits. A Single stage transistor amplifier has one transistor, bias circuit and other auxiliary components. The following circuit diagram shows how a single stage transistor amplifier looks like a weak input signal..See more on tutorialspoint
Introduction to the Amplifier an Amplifier Tutorial
In this Introduction to the Amplifier tutorial, we have seen that there are different types of amplifier circuit each with its own advantages and disadvantages. In the next tutorial about amplifiers, we will look at the most commonly connected type of transistor amplifier circuit, the common emitter amplifier.
