Question 1 of 27070

Where is the external feedback network connected to control the gain of a closed-loop op-amp circuit?

🔍 Key Concepts

• Negative feedback in op-amp circuits • Difference between inverting and non-inverting amplifier configurations • How closed-loop gain is set using resistive networks

💭 Think About

• Which op-amp input (inverting or non-inverting) is commonly used to sample the output and compare it to the input signal to control gain? • In a basic inverting amplifier, where is the feedback resistor connected relative to the op-amp terminals? • How does the choice of input for the feedback path affect the phase (inverting vs non-inverting) and stability of the amplifier?

✅ Before You Answer

• Identify which input is marked with the minus (−) sign and which with the plus (+) sign on an op-amp symbol • Recall that negative feedback is typically used to control closed-loop gain and stabilize the circuit • Verify which connection creates a feedback path that opposes changes in output, rather than reinforcing them (positive feedback)
