The schematic in Figure 1 is a common summing amplifier with multiple inputs and one single-ended output. It is a variation of a standard inverting amplifier. Point X is a virtual ground and is ...

Of all the pieces I have written over the life of this column the one that has drawn the biggest response from you, the readers, was the one on amplifier voltage offset (“Will the real offset voltage ...

There is an occasional caution that even unity-gain stable Voltage Feedback Amplifiers (VFAs) risk instability in inverting attenuator applications (Reference 1). In fact, there should be no more ...
