What is a two stage transistor amplifier?

The two stage amplifier circuit has two transistors, connected in CE configuration and a common power supply VCC is used. The potential divider network R1 and R2and the resistor Re form the biasing and stabilization network. The emitter by-pass capacitor Ce offers a low reactance path to the signal.

How does a two transistor amplifier work?

The two transistor amplifier offers a reasonably high impedance while providing a low output impedance. It is a simple circuit, yet operates effectively in scenarios where a little mroe gain is required than that which could be provided by a single transistor.

How do you use a transistor in a circuit?

One of the most common uses for transistors in an electronic circuit is as simple switches. In short, a transistor conducts current across the collector-emitter path only when a voltage is applied to the base. When no base voltage is present, the switch is off. When base voltage is present, the switch is on.

What is amplifier circuit?

It is a two-port electronic circuit that uses electric power from a power supply to increase the amplitude of a signal applied to its input terminals, producing a proportionally greater amplitude signal at its output. An amplifier is a circuit that has a power gain greater than one.

How do transistors work as amplifiers?

A transistor acts as an amplifier by raising the strength of a weak signal. The DC bias voltage applied to the emitter base junction, makes it remain in forward biased condition. Thus a small input voltage results in a large output voltage, which shows that the transistor works as an amplifier.

How does transistor amplify?

Transistors can amplify a signal because output power can be higher than input power. By applying a voltage or a current to one of the terminal pairs, there is a change in current through another pair of terminals. There are several different kinds of transistors at Topdiode.

What is an example of a transistor?

The definition of a transistor is an electronic device that works by controlling the flow of the electrical current. An example of a transistor is something combined in large numbers with microcircuits into a single circuit board and used in a computer. YourDictionary definition and usage example. “Transistor.”.

What is audio transistor?

Typically, an audio transistor is an amplification type transistor used to boost weak audio signals, such as in radios, to levels usable by other electronic devices, such as filters, equalizers, other amplifiers, and speakers. Standard audio transistors are typically NPN-type bipolar junction transistors.
