Many amplifiers exhibit an increase in voltage noise spectral density (NSD) as they approach the unity-gain crossover frequency. This noise peaking can cause your circuits to have 39% higher noise ...
Heavy load capacitance can cause the output of a unity-gain follower—an operational amplifier with direct feedback to the inverting input (Fig 1)—to ring and oscillate. The LM110 follower, for example ...
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 ...
