Feedback Amplifier Question 14 Detailed Solution Download Solution PDF. Feedback Systems: There are 4 possible combinations for Voltage and Current with which we can sample at the output and mix the feedback to the input. In a “positive feedback control system”, the set point and output values are added together by the controller as the feedback is “in-phase” with the input. The effect of positive (or regenerative) feedback is to “increase” the systems gain, i.e, the overall gain with positive feedback applied will be greater than the gain … See more In a “negative feedback control system”, the set point and output values are subtracted from each other as the feedback is “out-of … See more Thus far we have seen the way in which the output signal is “fed back” to the input terminal, and for feedback systems this can be of either, … See more Shunt-Series Feedback, also known as shunt current feedback, operates as a current-current controlled feedback system. The feedback signal is proportional to the output current, Io flowing in the load. … See more Series-Shunt Feedback, also known as series voltage feedback, operates as a voltage-voltage controlled feedback system.

It means that, voltage and current can be fed back to its input either in series or parallel. In the feedback connection types, the term 'voltage' refer to connecting the output voltage as input to the feedback ... WebMay 22, 2024 · If the information fed back to the input concerns the output voltage, the feedback tends to reduce changes in output voltage caused by disturbances (changes in load current), thus implying that the output impedance of the amplifier shown in Figure 2.15 a is reduced by feedback. Alternatively, if information about load current is fed back ...
