Recognising the non-inverting amplifier

Recognising the non-inverting amplifier

Circuit schematic of a non-inverting op-amp with Vin on the plus input, R_f from output to minus input, and R_1 from minus input to ground

In a non-inverting amplifier, the signal VinV_{\text{in}}Vin​ is connected directly to the +++ input of the op-amp. The output is fed back to the −-− input through RfR_fRf​, and R1R_1R1​ connects the −-− input to ground.

Step-by-step lessons on AQA A Level Physics non-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.
