What are the two components that makes up the collector current?

The 2 major current components are 1) the minority carrier diffusion in the base, and 2) generation and recombination current in the depletion region.

What are the current components?

This current consists of two constituents – Hole current (IhE) and Electron current (IeE). IeE is due to passage of electrons from base to emitter and IhE is due to passage of holes from emitter to base. Normally, the emitter is heavily doped compared to base in industrial transistor.

What are the current components of BJT?

A BJT consists of three differently doped semiconductor regions: the emitter region, the base region and the collector region. These regions are, respectively, p type, n type and p type in a PNP transistor, and n type, p type and n type in an NPN transistor.

Which component of the collector current IC is called the leakage current?

minority carriers
The collector current has two components: minority carriers and majority carriers. The minority current is called the leakage current.

What are the two basic types of transistors quizlet?

What are the two major types of transistors? NPN, PNP.

What accounts for minority component in collector current?

We know that the holes in the collector are the minority carriers, but they are the cause of considerable collector current.

What is the most important facts about the collector current?

What is the most important fact about the collector current? It is measured in milliampere. It equals the base current divided by the current gain.

Why does collector current increases with base current?

Collector Current It increases for larger emitter currents because the larger number of electrons injected into the base exceeds the available holes for recombination so the fraction which recombine to produce base current delines even further.

What are the current components in a pn diode?

We emphasize that the current in a p-n diode is bipolar in character since it is made up of both positive and negative carriers of electricity. The total current is constant throughout the device, but the proportion due to holes and that due to electrons varies with distance.

What are the types of leakage current?

There are two types of leakage current: ac leakage and dc leakage. Dc leakage current usually applies only to end-product equipment, not to power supplies.

What is leakage current in VLSI?

In deep submicron technology MOS transistor’s subthreshold current varies exponentially with gate-source voltage of the transistor. In CMOS circuits, very small current flows even with zero gate to source voltage (Vgs) and is termed as leakage current.

What is the relationship between collector current and base current?

Therefore, the collector current is related to the emitter current which is in turn a function of the B-E voltage. The voltage between two terminals controls the current through the third terminal. This is the basic principle of the BJT The collector current and the base current are related by

What is the difference between base voltage and collector voltage?

The small amount of current in the base controls the flowing of large current through emitter to collector region. The base voltage is generally 0.7V for Si and 0.3V for Germanium devices. Here the base terminal acts as input and the emitter- collector region acts as output.

How do you calculate collector current IC?

1st Way to Calculate Collector Current Ic. Using Known Values. If the base current, Ib, and β are known, then Ic can be computed by the following formula: Example If Ib=35μa and β=100, then Ic calculates out to be: 2nd Way to Calculate Collector Current Ic. Using Known Values

What is the collector-emitter voltage in anti-phase?

It can be seen that the Collector-emitter voltage is in anti-phase (–180 o) with the collector current. As the Base current Ib changes in a positive direction from 50μA to 80μA, the Collector-emitter voltage, which is also the output voltage decreases from its steady state value of 5.8 volts to 2.0 volts.
