The names for these different types of feedback systems are derived from the way that the feedback network connects between the input and output stages either in parallel (shunt) or …

Figure 1 shows a typical RF amplifier connection, while Figure 2 and Figure 3 show an ideal op amp, either current or voltage feedback, connected for non-inverting and invert-ing gains, …

Input current to the amplifier is the sum (the “mixture”) of input and feedback path currents. The feedback network samples the output voltage and contributes a current to correct the input.

Solution: Rin * Rin series feed-back is necessary; Rout * Rout voltage feed-back is necessary, So the applied arrangement: series voltage feed-back (see page 47).

The op-amp forces its positive and negative inputs to be equal; hence, the voltage at the negative input of the op-amp is equal to Vin. The current through the load resistor, RL, the transistor …

This type of Operational Amplifier provides the output voltage which is directly proportional to the changes in the input voltage. The output voltage is given by;

We illustrated this with the two basic negative feedback configurations: the inverting and the non-inverting configurations. In this section we will discuss negative feedback in a very general …
