What else can I help you with?
Why is it necessary to bias a transistor when it is to be used as an amplifier?
Biasing is necessary in a transistor circuit to keep the transistor working. Without proper biasing, the circuit will fail
Why fixed bias circuit is called so?
because we are not varying the biasing voltage
How does biasing occur in an integrated circuit?
It does not naturally occurs but it is designed with a certain bias to make it operational
How do you define transistor biasing?
Selection and setting of a transistor's operating pointto meet circuit functional requirements.
What are the types of FET biasing circuit?
Various FET biasing circuits are as follows: 1. Fixed bias 2. Self bias 3. Potential divider bias 4. Current-Source bias
Why are you going for different type of biasing the transistor?
In each of the biasing circuit ,there are variations in Q-point (undesirable)with respect to the temperature. The voltage divider bias serves a better way to minimize the change in Q-point.
Why capacitor is used in between the bias circuit?
Capacitor is used in biasing circuits to block the passage of DC signals.
Can a rectifier work either way?
if you are looking for the direction of rectifier than Yes. the rectifier convert the alternating current to one directional Direct current. It work as short circuit on the case of forward biasing and work as open circuit on the reverse biasing so it can work only in one direction.
Which biasing is known to as universal biasing?
voltage divider biasing
How biasing of FET differs from biasing of BJT?
in BJT forwardbiasing & reverse biasing are carried out but in FET voltage divider biasing &self biasing are carried out.
Why input gain of an amplifier is doubled from output gain?
The gain of a transister stage is determined by its biasing circuit design. The emitter of a transistor is affected by the input signal on the base. If the base forward biases the transistor, the emitter feels the potential of the colector. If the base reverse biases the transistor, the emitter is isolated from the collector and feels the potential of the emmiter biasing circuit. The output signal at the emmiter is representitive of the signal on the base, 180 degrees out of phase. The amplitude of the output signal will be larger, depending on the biasing circuit design.
What are the types of biasing in pn junction diode?
There are 2 type of biasing in PN junction didoe Forward biasing Reverse biasing
