The closed-loop voltage gain is reciprocal ofĮxplanation: Comparing the equation of closed loop voltage gain (AF) and the gain of the feedback circuit (B)... On what criteria does the feedback amplifier are classified?Įxplanation: The feedback amplifiers are classified according to whether the voltage or current is fed back to the input in series or in parallel.ġ8. Find the voltage-series feedback amplifier from the given diagram?Įxplanation: The mentioned diagram is the voltage-series feedback amplifier because the voltage across load resistor is the input voltage to the feedback circuit.ġ7. When load current flows into the feedback circuit, the configuration is said to beĮxplanation: In current-series and current-shunt feedback circuit, the load current flows into the feedback circuit.ġ6. Which of the following is not a feedback configuration?Įxplanation: In a feedback amplifier, either current or voltage can be fed back to the input, but both current and voltage cannot be feedback..
