What is difference between transistor biasing and connection?

Transistor biasing is a function of implementing a DC support circuit that places the transistor in an electrical region that produces the desired output signal in relation to its input signal, according to its design specification. A transistor can be biased to create a linear amplified signal proportional to its input. Biasing can also place the transistor into an easily saturated condition to propagate clipped binary output relative to its input. Biasing refers to the component configuration designed around a specific transistor family. Connection refers to the simple function of making an electrical junction between two conductors.


What is the function of resistor in single stage amplifier?

A simple, 1 transistor single stage amplifier can be made using several resistors to bias a NPN or PNP transistor into its' linear operating region. With this done, a small voltage signal applied to the input of the amplifier will have the voltage amplified at the output in a linear fashion. I'm not sure what your question is; if this does not answer it let me know.


What is difference between transistor and bias?

"Biasing" applies to transistor amplifier circuits. Simple amplifier circuits can only amplify positive signals. Negative signals cause the amplifier to shut down. However, AC signals in general have both a positive and a negative part. To allow a transistor to amplify AC, we add a positive voltage to the AC signal. Then after it is amplified, we remove the positive voltage again. The voltage, ac or dc on the base, compared to the emitter to cause operation of the transistor to conduct to the collector or to the emiiter in a NPN transistor.


Why op-amp symbol is a triangle?

Because that is the accepted convention. The triangle is the symbol for an amplifier, be it a differential amplifier with two inputs, such as an op-amp, or be it single ended, such as a simple transistor. The triangle symbol is used to show a block diagram of something that might have multiple things inside it, which the op-amp does. It is not generally used to represent a simple transistor, unless you were showing a block diagram. The triangle symbol is also used in digital logic diagrams, to indicate buffers (again, amplifiers), or inverters.


What are field effect transistors?

EMITTER, COLLECTOR, AND BASE The difference between a Field Effect Transistor and a regular transistor is that the regular transistor has PNP and NPN junctions and a FET has just a Drain Source Gate junction and is sensitive to static electricity just as not as bad as a MOSFET. Soldering a FET requires technical skill than it does a regular transistor. Transistors are used in switching and audio applications while FET's are used in RF VHF and HF applications and switching on high current devices such as LED's and piezo buzzers. So a one transistor radio using a PNP transistor does not mean you will pick up more stations you will just receive a weak audio voltage through the high impedance earphone from the simple diode circuit using a 9 volt battery. While FET's and MOSFET's will amplify the signal. MOSFET's are for really high current devices that's why have heat sinks on top of them.

Where you can use transistor?

Transistors are Bi-polar PN Junction devices (BJT's) which switch or amplify current and come in PNP and NPN types which dictate base to emitter bias conditions. BJT's commonly have three terminals b (base), e (emitter), and c (collector) which by internal design provide an hFE or dc current gain which is needed to produce larger currents from varying smaller currents. There are two p-n junctions : base/emitter and base/collector with BJT transistors. For this reason transistors are commonly used as simple current switches or amplifiers. Without the transistor there would essentially be no computers since there would have never been any mechanism by which to construct logic devices like OR Gates, AND Gates, NAND Gates, Flip-Flops, Inverters and Buffers. Transistor Switches In a simple switch application the transistor is placed in cutoff mode (off) or saturation (on). The on/off condition of a transistor is affected by a base-emitter bias versus the dc hFE. In a simple logic application where a digital signal is produced the NPN type transistors base-emitter bias current is high enough to saturate the transistors emitter-collection region with current. When the emitter collector region becomes saturated (both junctions forward-biased) a logic low (Vce =0) will be produced across the collector emitter terminals since current is flowing. By simply removing or lowering the base/emitter forward-bias current the transistor will move from saturation (Vce=0) to cutoff where the Vce is equal to Vcc.

What is the simple definition of saturation kinetics in biochemistry?

Saturation Kinetics- an enzyme reaction in which there is enough enzymes to constantly have a substrate bound them and therefore the reaction is occurring at Vmax. This velocity is only limited by the concentration of substrates, not the enzyme.


Oxygen Saturation results mean?

Oxygen saturation is the extent to which the blood is carrying as much oxygen as it is capable of doing. It is measured as a percentage. Oxygen saturation is the percentage of oxygen in the blood stream. Doctors become concerned when that percentage drops below 90%. It simple terms, at 82%, your brain other other organs are not receving enough oxygen to properly function. Anyone's oxygen saturation level varies from one moment in time to another. If you had a full copy of your sleep study report you might see reference to peak saturation (the highest saturation seen during the study), average saturation, saturation nadir (the lowest saturation recorded during the study), among other terms.
