Why CE transistor is more temperature senstive than CB transistor?
In CE transistor volteage divider biasing is used, which is independent of temperature and other parameters.
How transistor acts as a amplifier?
A transistor does not act as an amplifier. It is used as a component in an amplifier circuit.
Does a CD-ROM use a audio sensor to read data?
No the sensor is an LED and a photo-transistor.
Is BC557 a sensor?
No, it's a PNP general purpose transistor.
What is a function of a transistor in a fire alarm circuit?
A special sensor or transducer called a thermistor is used to detect an increase in the temperature of the surrounding air whenever smoke is produced by a fire. A different type of sensor is used to detect an increase in the size and density of particles in the surrounding air after it has been contaminated by smoke from a fire. Either sensor gives an output in the form of an increase in voltage whenever it detects an increased temperature and/or smoke particles. That increase in voltage is fed to the base of a transistor. When the voltage to its base increases, the current from the transistor's emitter to collector (or from its collector to emitter) increases and that increase in current operates the alarm. In other words, in a fire alarm circuit, the transistor acts as a switch which turns on the alarm whenever a sensor or transducer detects the presence of a fire, else it remains off.
What are the kinds of temperature sensors in automotive use?
1. Water temperature sensor Intake air temperature sensor cylinder head temperature sensor exhaus temperature sensor and catalytic sensor
What are the factors that affect the bias stability of a transistor?
temperature
Can a transistor can act like resistor capacitor inductor?
A transistor acts like a resistor when Gate is connected to Source.
What is junction temperature of the transistor?
The junction temperature is limited by the relationship between temperature and life, and the characteristics of the materials composing the transistor. Furthermore, transistors use minority carriers and thus are easily affected by temperature. In particular , if the temperature rises in a reverse-biased collector-base junction, carriers are generated without relation to the signal, the operating point shifts, and in the worst case thermal runaway occurs and the transistor becomes damaged. For this reason, the circuit must be designed so as to prevent the junction temperature from rising. Transistor deterioration occurs quickly when the junction temperature rises.
What is the measure of how a transistor reacts to changes in temperature?
The thermal voltage.
Why transistors are designed?
For switching applications transistor is biased to operate in the saturation or cutoff region. Transistor in cutoff region will act as an open switching whereas in saturation will act as a closed switch.
How operating point of transistor shifting?
Usually, the operating point of a transistor shift because of temperature induced gain or bias changes.
