Gain of a closed-loop op-amp circuit is determined by?

🔍 Key Concepts

• Closed-loop gain vs. open-loop gain of an op-amp • Role of the feedback network in setting gain • Difference between internal design of the op-amp and external components in a circuit

💭 Think About

• Ask yourself: when you design an amplifier for a specific gain, what do you actually change on the schematic: the op-amp part number or the resistors/circuit around it? • Think about how the gain formula for an inverting or non-inverting op-amp is written. Which elements appear in that formula? • Consider whether characteristics like supply voltage, slew rate, and maximum frequency usually set the gain, or just limit performance at extreme conditions.

✅ Before You Answer

• Identify which options talk about external components versus internal characteristics of the op-amp itself. • Recall that ideal op-amp gain equations use ratios of resistances (or impedances) to calculate closed-loop gain. • Verify that the option you choose is something a designer can easily change to adjust gain in a practical circuit.
