When testing transistors how much minimum voltage difference should be seen across the base-emitter junction?
It depends on the transistor. Minimum base-emitter junction voltage can be as low as 0.6 volts for a silicon transistor, and as low as 0.2 volts for a germanium transistor.
Why source cunneted to vdd in pmos?
In a PMOS transistor, the source is connected to the positive supply voltage (VDD) because it allows the transistor to turn on when the gate voltage is pulled low (below the source voltage). This configuration enables the PMOS to conduct current when the gate is at a lower potential, effectively allowing it to act as a switch in digital circuits. By connecting the source to VDD, the PMOS transistor can efficiently control the flow of current to the load connected to the drain.
What is offset voltage of Field Effect Transistor?
0.7V
What are the applications of jfet transistor?
The Junction Field Effect Transistor (JFET)exhibits characteristics which often make it more suited to a particular application than the bipolar transistor. Some of these applications are: - High Input Impedance Amplifier - Low-Noise Amplifier - Differential Amplifier - Constant Current Source - Analogue Switch or Gate - Voltage Controlled Resistor
What will be the output voltage if reference voltage is open circuited in a series voltage regulator?
unregulated voltage minus series regulator transistor drop.

Function of transistor BC 558 in musical bell?
it cnverts to a low voltage.
What is power transistor base emitter voltage?
Its is the emiiter base of the transistor voltage!
What is Collector Emitter saturation voltage?
Collector-emitter saturation voltage refers to the voltage drop across the collector-emitter junction of a transistor when the transistor is in saturation mode. It is the minimum voltage required to keep the transistor in saturation, where the transistor is fully turned on and conducting maximum current.

How many volts do you need for a transistor to be fully on?
A: By saturating a transistor meaning forward bias the base to emitter the voltage across the collector and base should be very low . depending on current it can be .050 v to .5v reversing or removing the bias voltage this voltage should be the same as the rail
What TTL Logic Voltage Level?
Historically, transistor-transistor logic (TTL) voltage levels have been 5.0 volts, with a high being any voltage above about 3.5 volts and a low being any voltage below about 1.5 volts, with lots of variations on the high/low cutoffs from part to part. Since about 2001, however, most processors have been using low-voltage TTL (LVTTL), which has a nominal voltage of 3.3 volts (approx >2.2 volts for high and approx < 1.2 volts for low). Hence, many parts advertised as "TTL" today actually work at 3.3 volts rather than 5.0 volts.

What is emitter biasing?
Emitter biasing is when you add a resistor between the emitter of a transistor and the 0v rail so that any voltage developed across the emitter will subtract from the voltage on the base and effectively turn the transistor OFF. We are talking about an NPN transistor and the transistor is an "ordinary transistor" or BJT (bi-polar Junction Transistor). For more information on transistor biasing see: Talking Electronics website.
What is offset voltage of Field Effect Transistor?
0.7V
Gm of a transistor is proportional to?
Gm of a transistor is proportional to Ie/Vt. That is, emitter current divided by thermal voltage.
