When both junctions of NPN diode are reverse biased then the diode is in which mode?
Transistor will be in OFF mode.
What is saturation and active region in a transistor?
The output current of a transistor is controlled by the current in the 'base' input: Increasing the control current will increase the output current in a more or less linear fashion. In the saturation region, this is no longer true: The transistor is nearing the limits of how much current it can conduct, so increasing the control current further has little or no effect. When using a transistor as an amplifier, you want to stay away from the saturation region as it would distort the signal you are amplifying. When using a transistor as an on/off switch, as in digital circuits, being in the saturated region is 'on' and a normal mode of operation.
What are the characteristics of a CB amplifier?
it is a mode of amplifier connection where the base part of the transistor is made common to both input and output.the circuit diagram is as shown below. the transiator gain(represented by the greek letter beta-B) is usually evaluated by the formula B=output current divided by input current. as we know that when the transistor is connected in common base mode the input pert will be emitter and the output part will be collector and we know that the collector current is quiet less than emitter current. as per the formula gain will be less than one. practically we consider emitter current as equal to collector current and hence B approaches 1 in case of common base mode amplifiers.as the gain is very less it is very less used as amplifiers. generally they use common emitter mode for amplification as this mode optimum amount of amplification.
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."
What percentage of the total current in a transistor flows through the collector?
The total current in a transistor is the emitter current, which is the sum of the collector current and the base current. The ratio of collector current over base current, in linear mode, is beta-DC, or hFe. However, in order for linear mode to be true, the ratings of the transistor must not be exceeded, and the collector current must not be limited by the circuit. Note also that hFe is temperature dependent, and is expressed in the data sheet as a minimum, not an absolute value - it can vary from transistor to transistor.
What is Sink and source mode of transistor?
Source mode at output provides safety than sink at output
What is invertion?
An inverting amplifier is one where the output is an inverted function of the input. The Class A transistor amplifier, also known as common-emitter, is inverting. As you increase the voltage on the base, the output voltage on the collector decreases. The operational amplifier has an inverting and a non-inverting input. In typical bridge mode, the output is inverted with respect to the (inverting) input, and the non-inverting input is used to reject common-mode input signals by moving the virtual ground point as needed.
Why does your amplifier keep going into protection mode?
A shorted output, bad output transistor. need more info.
Inputoutput and transfer characteristics of pnp and npn transistor in common base configuration?
result of output characteristics of npn transister in CB mode
What is the difference between nonlinear devices and linear devices?
In saturation region transistor acts as a non linear device i.e, there is no linear relation between input and output because in saturation region output does not change for variation in input. Whereas in other operating mode transistor acts as a linear device.
What transistor can be used in enhancement mode?
MOSFET can be used in enhancement mode

Current flow in transistor?
A; Must define the transistor type and its mode of application if you expect an answer. It has the capabilities to conduct both way on either type dueing saturation mode. Hope that helps
Are reflected waves always inverted?
In many models of wave motion reflected waves are inverted. Some models have another mode.
