Aug 31, 2016 On this channel you can get education and knowledge for general issues and topicsA seriesshunt feedback amplifier employs a basic amplifier with input and output resistances each of 2k and gain A1000 VV. The feedback factor 0. 1VV. Find the gain A f, the input resistance R if, and the output resistance R of of the closed loop amplifier. series shunt feedback circuit

Twoport analysis of feedback. There are four types of twoport network, and the type of amplifier desired dictates the choice of twoports and the selection of one of the four different connection topologies shown in the diagram. These connections are usually referred to as series or shunt

In Fig. R S and D Z form a simple SHUNT regulator as described in power supplies module 2. 1. In this circuit however, they are used to provide a stable voltage reference V Z at the base of Tr1. The emitter voltage of Tr1 will be typically about 0. 7V less than the base voltage and V OUT will therefore be at a lower voltage than the base. series shunt feedback circuit The feedback circuit is shunt because the output transistor (M2) has one of its possible output terminals on ac ground. Also, if R L R 4 goes to zero, i fb 0. SeriesShunt Example 1 Figure 1(a) shows the ac signal circuit of a seriesshunt feedback amplier. The input variable is v1 and the output variable is v2. The input signal is applied to the gate of M1 and the feedback signal is applied to the source of M1. Fig. 1(b) shows the circuit with feedback removed. A test current source itis added in shunt The Ideal Situation of the SeriesShunt Feedback Amplifier. zIdeal structure A circuit: a unilateral openloop amplifier. Ri: input resistance A: voltage gain Ro: output resistance circuit: an ideal voltagesampling seriesmixing feedback network The source and load resistances are included inside the A circuit. output controlled voltage source and its associated resistance connected in series), the feedback circuit will have (i) a series connection at the input, and (ii) a shunt (parallel) connection at the output. A rule of thumb is: the feedback connection at input matches
