What is the main advantage of common collector amplifier?

➢ The common-collector (CC) amplifier is usually referred to as an emitter-follower (EF). The input is applied to the base through a coupling capacitor, and the output is at the emitter. The voltage gain of a CC amplifier is approximately 1, and its main advantages are its high input resistance and current gain.

What are the advantages of CB amplifier configuration?

Due to its input-output impedance characteristics, the common base amplifier arrangement is extremely useful in audio and radio frequency applications as a current buffer to match a low-impedance source to a high-impedance load or as a single stage amplifier as part of a cascoded or multi-stage configuration where one ...

What is the advantage of having an emitter resistance in a common emitter amplifier circuit?

The aim of an AC signal amplifier circuit is to stabilise the DC biased input voltage to the amplifier and thus only amplify the required AC signal. This stabilisation is achieved by the use of an Emitter Resistance which provides the required amount of automatic biasing needed for a common emitter amplifier.

What is the disadvantage of emitter bias?

Disadvantages: reduced gain. The emitter resistor could be bypassed with a capacitor of adequate size to increase gain, but at the expense of increasing distortion or decreased linearity.

What is common base amplifier?

In electronics, a common-base (also known as grounded-base) amplifier is one of three basic single-stage bipolar junction transistor (BJT) amplifier topologies, typically used as a current buffer or voltage amplifier. ... The analogous field-effect transistor circuit is the common-gate amplifier.

What is the difference between common emitter and common collector?

Common Emitter Configuration – has both Current and Voltage Gain. Common Collector Configuration – has Current Gain but no Voltage Gain.

What are the advantages of differential amplifier?

Differential amplifiers offer many advantages for manipulating differential signals. They provide immunity to external noise; a 6-dB increase in dynamic range, which is a clear advantage for low-voltage systems; and reduced second-order harmonics.
