Output voltage swing is defined as the maximum positive or negative peak output voltage that can be obtained without wave form clipping, when quiescent DC output voltage is zero.

VOM is limited by the output impedance of the amplifier, the saturation voltage of the output transistors, and the power supply voltages. This is depicted in the figure above.

This emitter follower structure cannot drive the output voltage to either rail. Rail-to-rail output op amps use a common emitter (bipolar) or common source (CMOS) output stage. With these structures, the output voltage swing is only limited by the saturation voltage (bipolar) or the on resistance (CMOS) of the output transistors, and the load being driven.Maximum and minimum output voltage is usually a design issue when dynamic range is lost if the op amp cannot drive to the rails. This is the case in single supply systems where the op amp is used to drive the input of an ADC, which is configured for full scale input voltage between ground and the positive rail.

Because newer products are focused on single supply operation, datasheets use the terminology VOH and VOL to specify the maximum and minimum output voltage.

How can a radio use either source of current?

High precision op amp offers wider output voltage swing and noise.


What is the Effect of quiescent point close to cutoff?

The output voltage swing will not reach its maximum. This would then give clipping of one side of the signal which means the signal output is not a amplified representation of the original signal.


What is the effect of diode voltage drop as the output voltage?

The effect of diode voltage drop as the output voltage is that the input voltage will not be totally transferred to the output because power loss in the diode . The output voltage will then be given by: vout=(vin)-(the diode voltage drop).

On average the output voltage is 600 volts


Is it the value of input voltage equal the value of output voltage?

No. There are several factors that may affect the output voltage. For instance: Resistors, Transformer, Voltage regulators and others that can control the output voltage to a certain level.


What determines the output voltage and current of a transformer?

The ratio of output windings to input windings determines the ratio of output voltage to input voltage. The ratio of current is the inverse.


How can be a DC voltage source output voltage made half of its output voltgae?

By using something called a voltage divider.


How does an alternator know how much voltage output?

Output of the alternator is controlled by the voltage regulator.


How do rectifier circuits stabilize the output voltage when the input voltage is subject to fluctuations?

Rectifiers don't "stabilize the output voltage" of rectifier circuits when input voltage fluctuates. The rectifiers just rectify the input, and the output will fluctuate as the input does. Another form of "conditioning" of the rectified output is needed to address the issue of fluctuations. And we use the term regulation to talk about the effect of "stabilizing" an output voltage. Through regulation, the output will be resistant to changes in voltage when changes in the input voltage occur.


How does a voltage regulator regulate the voltage output of an ac generator?

Generator output is controlled by voltage feedback to the voltage regulator which senses voltage drop or rise and regulates the current being sent to the armature. This rise and fall of the armature current governs the generators output voltage.


Why clipping happen for op-amp?

Clipping occurs in the voltage waveform when the input voltage, multiplied by the voltage gain of the op-amp circuit, exceeds the op-amp supply voltage as limited by the output network. The supply voltage and output network, limits the maximum voltage that can be achieved at the output. The op-amp behaves normally within its range of maximum voltage output, and then it is clipped when it reaches the maximum voltage of the circuit.


How do you calculate the output voltage of a transformer if kva rating is known?

You can't determine the output voltage of a transformer by knowing kva. Transformers will be marked as to input and output voltages. Some will have multiple input and output voltages. The output voltage depends on the ratio of coil turns between input and output.


Why does the output wave shape give spike voltage?

Due to inductance there is a spike in output voltage


Why might the unloaded output voltage of a transformer be higher than its rms of 12.6v?

Because the windings of transformers have resistance, the primary and secondary currents will cause voltage drops. To compensate for the drops, the transformer may have been designed to have a higher than specified output voltage when there is little or no output current. The no load output voltage typically is only slightly greater than the specified voltage. Before measuring the output voltage, measure the input (line) voltage. If it is not as specified for the transformer, calculate its effect on the output.


What is meant by regulation or an alternator?

Regulation of an alternator is varying or adjusting the d.c. current flow (excitation current) in the revolving field coil to control the output voltage. When an alternator is subject to varying load conditions, and therefore changing load resistance at the output, the output voltage will vary in response. When output voltage is reduced in response to increased load (reduced output resistance), the "voltage regulator" will respond by increasing the excitation current to increase the voltage output. If load is reduced, the generator will momentarily become over-excited and the ouput voltage will increase. The voltage regulator responds by decreasing excitation current, returning the generator output voltage to its nominal level.

What is voltage gain?

Voltage gain is the ratio of the output voltage of an amplifier to its input voltage.


What are the output voltage and current of a transformer determined by?

The secondary (output) voltage is determined by the primary voltage and the turns ratio of the transformer. The secondary current is determined by the secondary voltage and the load resistance.

The output voltage of a generator is verid by varying the field excitation of the generator


Why is output dc higher than input ac?

Output power can never be more than input power. With a transformer, it is possible to increase the output current (while decreasing the output voltage), or to decrease the output current (while increasing the output voltage).


Why is dual supply used for op-amp?

Dual supply arrangement allows for the output voltage to swing both above and below zero volts, and also gives an output of 0V when there is no voltage difference between the two inputs. An op amp can only amplify a signal to its values in the supplied range. If you want to amplify a signal with negative values then you need a negative supply.
