Low VT (threshold voltage) transistors are designed to switch on at lower gate voltages, resulting in faster operation and reduced power consumption, making them ideal for low-power applications. High VT transistors, on the other hand, require a higher gate voltage to turn on, which helps reduce leakage current and improves stability, making them suitable for high-performance and high-speed applications. The choice between low and high VT transistors often depends on the specific requirements of the circuit, such as speed, power efficiency, and leakage control.

What is the characteristics of transistor?
the name itself we can say that the transistors are used to transfer from low resistance to high resistance.
Why output impedence is high in opamp?
Output impedance in an op-amp is not high - it is low - input impendance is high, and this is because the input stage transistors have high gain.
What are power transistors?
Power transistors are transistors that are used in high-power amplifiers and power supplies.
Can you see transistors?
Basically, in transistor, the signal is transferred from low resistance circuit to the high resistance circuit. So it is called transfer+resistor=Transistor.Transistors are widely used in different types of switching, amplifiers, oscillators and integrated circuits.Based on the applications, the types of the transistors are as given below:General purpose transistors, Low frequency transistors, High frequency transistors, Power transistors, Switching transistors, Field Effect Transistors, MOSFET, Uni-junction Transistors, Bi junction transistors, Photo transistor, High power transistors, Complementary pair, Darlington amplifier, Video and R.F. amplifier, Ultrahigh frequency and microwave, Insulated gate bipolar transistors, Static induction transistors.More their to know about transistors are as given below:History of invention, Time-line throughout, Basic construction, Bias arrangement, working, Various currents in transistors, Basic transistor amplifier, Configurations, Characteristics, Current gain and relation among them, D.C. load line, Operating point, Biasing of transistor, stability factor, specifications and ratings, testing, colour coding, identification of transistor using multimeter, h-parameter of transistor, particular applications etc...

What are sleep transistors?
A rest transistor is either a pMOS or nMOS high VT transistor and is utilized as a change to close off force supplies to parts of a configuration in standby mode. The pMOS rest transistor is utilized to switch VDD supply and henceforth is known as a "header switch."
Is transistor Low voltage?
Transistors can operate at low voltages, but the term "low voltage" is relative and depends on the specific application and type of transistor. For instance, many modern digital circuits use low-voltage transistors designed to operate effectively at voltages below 1.8 volts, while others may function at higher voltages. Overall, transistors are versatile components that can be designed for a range of voltage levels depending on their intended use.
What are the three kinds of switching mechanism used in low voltage?
Transistors, relays, and triacs.
Can PNP transistors be used in place of TIP31 transistors?
No...TIP31 is NPN. The complementary PNP is a TIP32. They are both large high power (40W) devices.
How many transistors are fitted into a CPU today?
As of the end of 2016, high end multicore microprocessors have from 3,000,000,000 to 8,000,000,000 transistors. But there are plenty of other medium range microprocessors and microcontrollers with much fewer transistors being manufactured.
What advantage over vacuum tubes did transistors represent in computer design?
From an audio amplifier standpoint, transistors were primarily low-voltage, high current devices. Since loudspeakers were typically low-impedance, the transistorized circuit didn't require a transformer to help match the impedance; i.e. they were better matched. However, when a transistor "saturated" it "clips" abruptly, causing harmonics at the output. Vacuum tubes tended to "soft clip' which reduced the undesirable harmonics. From another standpoint, transistors were smaller in size, didn't require high voltage power supplies, and dissipated less heat (i.e. more efficient).
