Transistors need thermal stabilization because the operating point of a transistor junction, similar to a diode, is affected by temperature. In fact, this can cause thermal runaway, and device destruction, if the circuit design does not compensate for this.
Answer mostly correct but the operating point of a transistor must remain fixed as temperature varies whether going low or higher. that is mainly the concern about. not runaway that is caused by bad design.

∙ 11y agothere are several stability issues on transistors.
1- Thermal stability : stability of temperature of transistors.
2- Oscillation stability: stability of circuit of transistors. sometimes if circuit design is not good, some transistors in a circuit starts to oscillate, In condition that thy does not need to oscillate.
3- Bias stability: stability of DC voltages of transistors (with temperature changes).

How does using a transistor with a different beta affect the operation of the common emitter amplifier?
Gain, in the common emitter amplifier, is beta (hFe) or collector resistance divided by emitter resistance, whichever is less. Substituting a different beta (hFe) transistor will affect gain, if hFe is less, or increase stability and design margin, if hFe is greater.
What are the factors that affect the bias stability of a transistor?
temperature
Factors responsible for stability of quiescent point?
Biasing of the transistor is responsible for stability of Q point.
What is thermal stability of transistor?
The thermal stability is the ability of the transistor to withstand changes in temperature without the transistor's parameters changing. Transistors generally have poor thermal stability and in particular the Beta parameter increases with temperaure, which can cause thermal runaway in a badly designed circuit. This is well known and the bias current in transistors is normally stabilised by the application of negative feedback in proper circuit design.
Factors that affect frequency stability and amplitude stability of oscillator?
Practically, there are some factors that affect the frequency stability of Variation in temperature Oscillator • Circuit Components - Values of R, L and C changes with temperature • Transistor Parameters - causes variation in transistor parameters • Supply Voltages - Variations in power supply • Stray Capacitances • Output Load - Variations of load causes a change in effective resistance • Inter‐element Capacitance
What is Si transistor?
A silicon transistor is a transistor made of silicon.
Is active is a cutoff region of transistor?
The active region of a transistor is when the transistor has sufficient base current to turn the transistor on and for a larger current to flow from emitter to collector. This is the region where the transistor is on and fully operating.
What is the purpose of the Unijunction Transistor?
A Unijunction Transistor is a transistor that acts solely as a switch.

Different between power transistor and transistor that used in small signal?
Power transistor can conduct large amount of currents through it, more than small signal transistor. power transistor has a vertical structure and small signal transistor has horizontal structure.In power transistor quasi saturation region is present which is absent in the small signal transistor. In power transistor there is a inculsion of drift layer which is not there in the small signal transistor. Power dissipation is less in power transistor and it is more in small signal transistor. b.v.polytechnic,vasai pushkar vaity.
