explain why nonlinear distortion exists in a CE AMPLIFIER with a large output signal
Envelope 10a. Briefly state why loudspeakers for high frequencies (treble) are small, whereas for low frequencies (bass) are large. b. If an input signal into an amplifier is amplified too much (i.e., saturated), its amplitudes will be clipped, as shown below. This will lead to what is referred to as harmonic distortion. Amplifier Briefly explain why this causes a distortion in the output signal and the nature of this distortion.
4. The MOSFET amplifier below must amplity s sinusoidal input signal, wh minimal distortion. a) Determine the smallest value for Vas-Vi for minimal distortion under the small-signal condition for the given v Tos Tas b) Determine the minimum voltage VaD across the drain resistor for a voltage gain of 10. c) Determine the smallest value for Vos that would be required in order to amplify vg with minimal distortion. What should be the minimum required voltage for the power supply...
Question 2: [18] 2.1: 2.1.1: Negative feedback in signal amplifiers are utilized to improve distortion and to enhance the frequency response/bandwidth of the amplifier. Only voltage gain is sacrificed. In figure 2, negative feedback in a signal amplifier is represented in a block diagram form. Redraw the circuit, give a name to every connection and deliver an explanation how it works, how the original output "opposes" the original input to limit the gain and to employ negative feedback. [6] +...
Explain, in your own words and without any detailed circuit analysis, why the CE-CB cascode amplifier extends the upper frequency range of the corresponding CE amplifier. Your explanation should take no longer than half a page and should cover the following points: The disadvantage of using a CB amplifier on its own Why is the 3 dB cut-off larger for the CE when in cascode than when it is on its own? What is the role of the CB stage...
