The inverting configuration is one of the fundamental applications of operational amplifiers, often referred to as op amps. When studying operational amplifiers, after understanding the ideal model, the inverting and non-inverting input terminals, and the concept of feedback, the inverting…

This article provides an in-depth look at the non-inverting configuration of operational amplifiers, as a natural continuation of the introductory guide to op amps (available in Italian: Amplificatori operazionali: caratteristiche e utilizzi). In a non-inverting amplifier, the signal is applied…

Before you start: transformer and 230 V mains Safer source: a function generator, as used for the measurements in this article, or a certified low-voltage AC adapter lets you run the experiment without any contact with the mains. Transformer: if…

Before you start: oscilloscope measurements on the bridge Probe ground: the ground clip of a bench oscilloscope is connected to mains earth. If the function generator is earthed too, clipping the probe ground to a node of the bridge shorts…
