Output Transistor
Why collector terminal is used to get output?
In transistors with configuration both as common emitter and common collector, the collector terminal is used to get output. Is there any special reason in physics for using collector terminal as output terminal?
In transistors with configuration both as common base and common emitter, the collector terminal is used to get output. Why can't we take emitter as an output terminal in common base configuration and base in common emitter configuration?? Is there any sound reason in physics for this??
What you've described is the beauty of the bipolar transistor. Assuming a high Early voltage, in common emitter configuration you can impart a voltage signal on the collector and you get no signal going back to the base (assuming no Cbc effects).
Same if you impart signal on the collector of a common base transistor you get no change in the emitter output.
From a device physics perspective as long as the collector has an electric field that sweeps the minority carriers out of the base and into the collector, the transistor maintains normal forward bias operation. The collector voltage can range from very large reverse bias - to near breakdown, all the way to slightly forward bias and just utilize the built-in electric field and still sweep out all the base minority carriers. This large range of voltage while still maintaining the output collector current provides a near ideal current source that provides a very good output for the device.

Pass Transistor Logic $65.33 Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. In electronics, pass transistor logic (PTL) describes several logic families used in the design of integrated circuits. It reduces the count of transistors used to make different logic gates, by eliminating redundant transistors. Transistors are used as switches to pass logic levels between nodes of a circuit, instead of as switches connected directly to supply voltages . This reduces the number of active devices, but has the disadvantage that output levels can be no higher than the input level. Each transistor in series has a lower voltage at its output than at its input. If several devices are chained in series in a logic path, a conventionallyconstructed gate may be required to restore the signal voltage to the full value. By contrast, conventional CMOS logic always switches transistors to the power supply rails, so logic voltage levels in a sequential chain do not decrease. Since there is less isolation between input signals and outputs, designers must take care to assess the effects of unintentional paths within the circuit.

Transistor Circuits for Spacecraft Power System $345.71 As a standalone volume, Transistor Circuits For Spacecraft Power System presents numerous transistor circuits and building blocks associated with power electronics in general, and examines the major subsystem components for solarbased spacecraft power systems. The technique and concept, of continuity of states for nonlinear circuits handling power transfer under cyclic excitation is introduced in Part I and further developed throughout the book. This powerful technique employing matrix formulation bypasses eigentransients and yields steadystate responses rapidly. Closedloop treatments are also given for largescale linear circuits, many closedform solutions for control loopgain, conducted susceptibility, output impedance, etc. are covered. Extensive mathematical procedures are retained to highlight the importance of analytical flows.The author also reviews the evolution of solarbased spacecraft power systems; introduces modes of operations: discharge (boost), shunt, and charge; and covers pulsewidthmodulated (PWM) boost power converter for both DC and AC conditions. A configuration tree for shunt mode operation is conceived. Based on the configuration tree, the best topologies, sequential PWM shunt and rippleregulated freerunning shunt, are intensively examined and formulated.Transistor Circuits For Spacecraft Power System provides important information for understanding the relationship between earthbound semiconductor circuits and space borne vehicles.

Transistor Radio $68.51 High Quality Content by WIKIPEDIA articles A transistor radio is a small transistorbased radio receiver.Bell Laboratories demonstrated the first transistor on December 23, 1947.After obtaining patent protection, the company held a news conference on June 30, 1948, at which a prototype transistor radio was demonstrated. There are many claimants to the title of the first company to produce practical transistor radios, often incorrectly attributed to Sony (originally Tokyo Tsushin Kogyo). Texas Instruments had demonstrated alltransistor AM (amplitude modulation) radios as early as 1952, but their performance was well below that of equivalent vacuum tube models. A workable alltransistor radio was demonstrated in August 1953 at the Dsseldorf Radio Fair by the German firm Intermetall. It was built with four of Intermetalls handmade transistors, based upon the 1948 invention of Herbert Matar and Heinrich Welker However, as with the early Texas units (and others) only prototypes were ever built; it was never put into commercial production.

Thin Film Transistor $90.81 High Quality Content by WIKIPEDIA articles A thinfilm transistor (TFT) is a special kind of fieldeffect transistor made by depositing thin films of a semiconductor active layer as well as the dielectric layer and metallic contacts over a supporting substrate. A common substrate is glass, since the primary application of TFTs is in liquid crystal displays. This differs from the conventional transistor where the semiconductor material typically is the substrate, such as a silicon wafer.

The Importance Of Current Sense Resistor In Switch Mode Power Supply
Current sense resistor is usually located in the switch mode power
supply section. Newer version of monitor-the b+ (boost) circuit
also have this current sense resistor. If you repair electronic
equipment especially the switch mode power supplies, the current
sensing resistor is connected to the source pin of power FET (field
effect transistor) and the other end to HOT GROUND. The value of
current sense resistor is in the range of 0.1 ohm to about 1 ohm.
The values are depends on the design of each power supply.
In monitor power supply where pulse width modulation (pwm) ic UC3842
are used. Pin 3 of this power ic is called I-sense which means
current sense and this pin is connected to source pin of POWER FET.
The purpose of this current sense circuit is for overcurrent protection.
This circuit usually samples the voltage drop across a resistor in series
with the switching fet transistor. If the current rises abnormally due to
some short circuit in the secondary side such as a shorted secondary diode
or horizontal output transistor (HOT), the voltage will exceed a reference
level and shutdown the pulse generator which is the PWM ic. This circuit
provides protection to components in the event a problem occurs.
In some cases where overload happen-the power section will blow and
most of the time the components changed are fuse, power fet, pwm ic,
zener diode and current sense resistor.
Do you know that a small change in this current sense resistor value
have a great impact on the secondary output? A little change in value
say from 0.22 ohm to 0.44 ohm can caused your ouput voltage to drop
into half! I have seen a lot of repairer can't detect this type of
problem (low output voltage) due to that they used analog or digital
meter that don't have the low ohms range. You can't differentiate
if the low ohms resistor has its value changed by using normal meters.
I personally use the Dick Smith ESR Meter which have the capabilities
to check resistor value down to 0.01 ohm! If you don't have this
special meter you may just direct replace the current sense resistor
to see if the generated secondary output will back to normal voltage.
Another tip is that if the current sense resistor in the monitor
B+ circuit have changed value it will caused the output in the
boost circuit to become low and you will have a small width display
and of course the high voltage will become low as well. Instead of
24Kv it becomes 15-18Kv.
