Question

Figure 2 shows a feedback amplifier circuit. Rs is the source resistor and R, is the load resistor RS Vs VI RL OPAMP R2 R1 RM R3 R4 Step 1: open-loop and closed-loop circuits identification 1.1 Identify the source, the load, and the closed-loop amplifier 1.2 Identify the open-loop amplifier (**A" eireuit) and the feedback network (B" eircuit) in the closed-loop amplifier 1.3 Identify the connection type between the "A" circuit and the "B" circuit at both the input and the output - i.e. feedback topology 1.4 Select the appropriate v or i for xo,Xi,Xf and xs, according to the feedback topology (you can refer to slide #6) 1.5 Convert the signal source connected at the input according to the mixing topology Current mixing: use current source Voltage mixing: use voltage source Ww + >
