What is the output characteristics of a transistor?
Characteristics of Transistor Output Characteristic – This is a graph of Output Current on one axis and Output Voltage on another, at a constant Input Current. Current Transfer Characteristic – This is a characteristic curve that points to the fluctuation of the Output Current to that of the Input Current.
What is the input and output characteristics of a common emitter NPN transistor?
In Common Emitter (CE) configuration, the emitter is the common terminal. Hence, the input is between the base and the emitter while the output is between the collector and the emitter. Two terms that you must remember: Input characteristic – the variation of the base current (IB) with the base-emitter voltage (VBE)
What are the characteristics of output?
Output Characteristics: The curve is got by plotting the output current against output voltage keeping the input current constant. Current Transfer Characteristics: This characteristic curve describes the variation of output current in accordance with the input current, keeping the output voltage constant.
What are the characteristics of a PNP and NPN transistor?
PNP transistor is made up of two P-type material layers with a layer sandwiched of N-type. The NPN transistor is made up of two N-type material layers with a layer sandwiched of P-type. In an NPN-transistor, a +ve voltage is set to the collector terminal to generate a flow of current from the collector.
What are the inputs and outputs of a transistor?
A transistor is a three-terminal device that contains a base, emitter and collector. In a common-emitter configuration, the input voltage is applied between emitter and base terminals and the output voltage is applied across the emitter and collector terminals.
What is the output voltage of transistor?
Here’s how I would approach it: The base-emitter junction of a BJT behaves very much like a regular diode. So under typical circumstances, there is a ~0.7V drop from the base to the emitter. In other words, the voltage at the top of R1 will be about 0.7V less than the voltage at the top of R2.
What is output characteristics of CE configuration?
In CE configuration the curve draws between collector current IC and collector-emitter voltage VCE at a constant base current IB is called output characteristic.
In which region of output characteristics of transistor it is used as switch?
When a transistor works as a switch it works in cut-off and saturation regions. In the cut-off state, both emitter-base junction and the collector-base junctions are reverse biased.
How the NPN differs from PNP transistor?
NPN and PNP transistors have very similar schematic symbols. The only difference is the direction of the arrow on the emitter. In a NPN (on the left) it points outward, for a PNP (on the right) it points inward.
What is input and output resistance?
The input and output impedance of an amplifier is the ratio of voltage to current flowing in or out of these terminals. The input impedance may depend upon the source supply feeding the amplifier while the output impedance may also vary according to the load impedance, RL across the output terminals.
