Why collector base junction is always reverse biased for normal operation of transistors?
collector junction is reverse biased so as to remove the charge carriers away from its junction with the base.
A transistor is in active region when?
a transistor in active region when emitter junction is forward biased nd collector junction is reverse biased
What is the biasing technique in transistor for it to be in active region?
For a transistor to be in active region : Base Emitter junction should be forward biased and Emitter collector junction should be reverse biased.
A PNP transistor is connected in a circuit so that the collector-base junction remains reverse biased and the emitter-base junction is forward biased This transistor can be used as a power amplifier?
Yes1
Why is the collector of a transistor connected to the base or heatshink?
Because most of the heat buildup occurs in the reverse biased collector-base junction where Ic = Ie + Ib flows.
When both junction of npn diode reverse biased the the diode in what state?
reverse biased
Why collector base junction is always reverse biased for normal operation of transistors?
collector junction is reverse biased so as to remove the charge carriers away from its junction with the base.
A transistor is in active region when?
a transistor in active region when emitter junction is forward biased nd collector junction is reverse biased
Is pn junction act as switch in reverse biased condition?
yes
What is junction capacitor in integrated capacitors?
reverse biased PN junction MOS capacitors are more common
When the both junction of NPN diode is reverse biased then the diode is mode?
cutoff
What is the biasing technique in transistor for it to be in active region?
For a transistor to be in active region : Base Emitter junction should be forward biased and Emitter collector junction should be reverse biased.
Why the resistance of forward bias is equals to zero nd resistance of reverse bias is infinite?
the junction is conducting when forward biased, approaching zero resistancethe junction is nonconducting when reverse biased, approaching infinite resistanceneither is exactly zero or infinite
A PNP transistor is connected in a circuit so that the collector-base junction remains reverse biased and the emitter-base junction is forward biased This transistor can be used as a power amplifier?
Yes1
Why is the input impedance of a jfet so high?
If you mean JFET, it is because the gate junction is reverse biased.
Why should a JFET be operated with only reverse bias on the gate?
If the gate-channel junction of a JFET was not reverse biased the JFET would just act as a forward biased diode across that junction and the gate would cease to have any control over the channel conductance. For the same reason in a MOSFET the substrate-source/channel/drain junction must remain reverse biased. The MOSFET could not act as a MOSFET.
When the both junction of npn diode is reverse biased then the diode in which mode?
Transistor will be in OFF mode.
