External resistor of a differential amplifier is connected in series combination with each emitter. Why is it mandatory to use or connect a level translator cir If the car starts going up a hill and slows down, the voltage difference would be amplified, and the output of the differential amplifier can be sent to an actuator, which moves a lever to increase the rate of fuel going to the engine.

The use of swamping resistor in differential amplifier

Since at the output there is a dc error voltage, therefore, to reduce the voltage to zero, this configuration is normally followed by a level translator circuit.

Split and merge into it. The output is referred to as an unbalanced output because the collector at which the output voltage is measured is at some finite dc potential with respect to ground.

Numerical on Non-Inverting Amplifier. Resistor placed in the emitter lead of a transistor circuit to minimize the effects of temperature on the emitter-base junction resistance. If a differential amplifier stage has collector resistors of 5.


When you get back to the desired speed, the difference is zero, and the actuator stops moving.

If these features are not important for your design, then the added complexity of resisfor usually requiring a positive and negative voltage, multiple transistors, etc. The value of R’ E is usually large enough to swamp the effect of r’ e. Due to this configuration, the dependability of voltage gain which varies in accordance to changes in emitter resistance can be ablated.

Noise inherently will be added onto both of these lines, but the noise will tend to be in the same direction for both. When an amplifier is swamped the voltage gain … to the output is less dependent on the load.

What is meant by swamped amplifier? Merge this question resistof. If your speed increases too much, then it would have a negative voltage, so the actuator would move the other way, decreasing the rate of fuel to the engine.

In series with each collector c. IT also helps to increase the sign … al to noise ratio. It also increases the linearity range of the differential amplifier.

What is the connection configuration of swamping resistor in case of a differential amplifier ?

Amplofier parallel with each emitter Correct Answer: What is the connection configuration of swamping resistor in case of a differential amplifier? In parallel with each collector d. A differential amplifier is actually a very advanced … and good!

Which of the following AC parameters of an Op-amp results in The output voltage gain in this case is given by The voltage gain is half the gain of the dual input, balanced output differential amplifier.


Would you like to merge this question into it? In this case, two input signals are given however the output is measured at only one of the two-collector w. When you set the cruise control, a voltage level can represent the speed that the car was traveling when set.

In series with each emitter b. What are the disadvantages of differential amplifier?

Basically the function resisfor a resistor is always to oppose the flow of current through it and the strength of this opposition is termed as its resistance.

From a signal to noise ratio, a differential amplifier is also a cut above if implemented correctly and designed well.

A differential amplifier could be used in a cruise control on a car. What will be the output voltage of an Op-amp inverting adder Why using bypass capacitor across emitter resistor in transistor amplifiers? A differential amplifier has a high “common mode rejection”, which means if the same voltage is applied to both inputs, the output will not change it only amplifies the difference between the inputs.

What are the industrial applications of integrator and differentiator circuits using operational amplifier? This is useful resiztor control systems, where one signal can represent what is actually happening could be … a position or speed, for example.
