How are signal swings calculated?

How are signal swings calculated?

For example you might be asked for an amplifier for an input voltage up to 1Vrms and a gain of 10. The input signal swing is then +/- sqrt(2) * 1V, or +/-1.4V, or 2.8V p-p. The desired output signal swing is this range * gain, or +/-14V peak.

What is the swing in BJT?

Swing is the difference of maximum output voltage and minimum output voltage. Maximum possible swing in output you can have is VDD-VSS.

What is the maximum allowable output voltage swing?

For an audio circuit, the maximum output voltage swing would be the difference between the maximum positive and maximum negative voltage levels. That is, it is the possible peak-to-peak voltage of the waveform.

How do you find the maximum output of a swing?

1. Ve min = 0V in theory …!
2. Ve max 9.7 with Vce(sat)=0.3 thus Vb= 10V-0.3 +Vbe= 10.4.
3. thus max swing is 9.7V with load fixed above.

How do I increase swing output?

Increase the output voltage swing of an op-amp using two methods. Bootstrapping the op-amps power supply pins to make it have a dynamic voltage range, and adding an external gain stage with larger rails.

What is the maximum output voltage swing and operational amplifier?

For an op-amp with a voltage gain (AV) of 200,000 and a maximum output voltage swing of +15V/-15V, all it would take is a differential input voltage of 75 µV (microvolts) to drive it to saturation or cutoff!

What is the maximum output voltage swing an op-amp 2 points?

Explanation: The value of power supply for 741 op-amp=±15v. Therefore, the ideal maximum output voltage swing for an AC amplifier with single power supply = +Vcc = +15v.

What is output swing in opamp?

Output Voltage Swing defines how close the op-amp output can be driven to rail to rail (either power rail: VDD or VSS) under defined operating conditions where the op-amp still can function correctly. The smaller the output short circuit current is, the closer the amplifier will swing to the rail.

What is output swing?

Output Voltage Swing It is the maximum positive or negative output voltage that can be obtained without wave clipping. This will vary depending on the output load impedance and supply voltage. Typical output voltage swing of 741 opamp is ±14V when the supply voltage is ±15V and load impedance is greater than 10KΩ.

What is the maximum output voltage swing and op-amp?

What is peak to peak swing in a BJT transistor?

Peak to peak swing is the swing on the side that clips first X 2. Maximum swing is obtained when the at rest DC voltage is about 60\% of the rail to rail supply voltage. Can the emitter and collector terminals of a BJT transistor be interchanged?

What is the voltage of a BJT amplifier?

There is a website called thesignalpath.com where a BJT amplifier is described. The set up is a BJT with a collector resistor, an emitter resistor, 2.5V and -2.5V supplies, and we’re taking the output off the collector. The BJT has a Vce,sat = 0.2V According to the website

What should be the swing in the signal in a transistor?

For resistive loads: Swing in the signal should be such that at negative peak of the signal, collector voltage is large enough to avoid operation in non-linear portion of the transistor characteristics. For inductive loads: (1) same as mentioned above.

How do you determine the maximum output voltage of a collector?

It’s determined by the value of the power supply, whether there’s an emitter resistor, and the bias point of the collector voltage. For example, the maximum would be if there were no emitter resistor and the collector was biased at 1/2 the supply voltage.
