  Does Your Op Amp Oscillate? &mdash AN148
  PDF, 2.0 Mb, File published: Oct 9, 2014
  We analog designers take great pains to make our amplifiers stable when we design them, but there are many situations that cause them to oscillate in the real world. Various types of loads can make them sing. Improperly designed feedback networks can cause instability. Insufficient supply bypassing can offend. Finally, inputs and outputs can oscillate by themselves as oneport systems. This article will address common causes of oscillation and their remedies.

  Does Your Op Amp Oscillate?
  Barry Harvey, Staff Design Engineer, Linear Technology® Corp. Well, it shouldn’t. We analog designers take great pains
  to make our amplifiers stable when we design them, but
  there are many situations that cause them to oscillate
  in the real world. Various types of loads can make them
  sing. Improperly designed feedback networks can cause
  instability. Insufficient supply bypassing can offend. Finally,
  inputs and outputs can oscillate by themselves as oneport systems. This article will address common causes
  of oscillation and their remedies.
  Some Basics
  Figure 1a shows the block diagram of a non-rail-to-rail
  amplifier. The inputs control the gm block which drives the
  gain node and is buffered at the output. The compensation
  capacitor CC is the dominant frequency response element. + +
  gm INPUTS – OUTPUT +1 – CC The return of CC would go to ground if there were such a
  pin; however op amps traditionally have no ground and
  the capacitor current will return to one or both supplies.
  Figure 1b is a block diagram of the simplest amplifier
  with rail-to-rail output. The input gm’s output current is
  sent through a current coupler that splits the drive current between the output transistors. Frequency response
  is dominated by the two CC/2s, which are effectively in …
