The circuit and what it does

Circuit schematic of an inverting op-amp amplifier with input resistor, feedback resistor, grounded non-inverting input, virtual-earth junction, and output label

An inverting amplifier uses negative feedback to make an op-amp stable and predictable. The input signal goes through RinR_{\text{in}}Rin​ to the inverting input, the non-inverting input is grounded, and RfR_fRf​ feeds part of the output back to the same junction.

  3. /inverting amplifier configuration (A-level only)

Step-by-step lessons on AQA A Level Physics inverting amplifier configuration (A-level only). Each one builds up to exam-style questions. Physics is one of the most mathematically demanding A Levels -- at least 40% of the marks require maths skills at Level 2 (GCSE) standard or above, so build calculation and graph-handling fluency alongside the conceptual content from the start.
