A common collector, also known as an emitter follower, is a basic transistor amplifier configuration where the collector terminal is common to both the input and output. In this setup, the input signal is applied between the base and the emitter, while the output is taken from the emitter. This configuration provides high input impedance and low output impedance, making it useful for impedance matching and signal buffering. Additionally, it offers voltage gain close to unity, meaning the output voltage closely follows the input voltage.

In a common collector circuit input resistance is?
In a common collector circuit, also known as an emitter follower configuration, the input resistance is typically high. This high input resistance is due to the transistor's configuration, where the input is applied to the base and the output is taken from the emitter. The input resistance can be approximated as β (beta, the current gain) multiplied by the emitter resistor (if present), making it much higher than the resistance looking into the collector. This characteristic makes the common collector circuit suitable for impedance matching applications.

What is common collector bipolar junction?
A circuit in which the input signal is applied to its base and the collector is earthed (grounded) is known as common collector configuration of BJT (BiPolar Junction Transistor)
Why is common emitter is greater than common collector?
Common-emitter gives more voltage gain because a common-collector amplifier has a voltage gain of 1. But a common-collector can have a power gain because the input impedance is much more than the output impedance.
What is the input current for common collector?
from the name itself the common collector has its collector terminal in common with both the input and output circuits of a transistor and the base current is chosen as the input current and the output current is the emitter current
What is the voltage gain of common collector?
unity
Is collector a common noun?
Yes, "collector" is a common noun. It refers to a person who gathers or accumulates items, such as stamps, coins, or art. Unlike proper nouns, which name specific individuals or entities, common nouns like "collector" can refer to anyone who fulfills that role.
