The Op Amp's Place in the World [chapter]

Bruce Carter
2013 Op Amps for Everyone  
There really wasn't much call for electronic feedback design until computers and transducers become of age.  ...  It seems that circuits designed with large open loop gains sometimes oscillate when the loop is closed.  ...  Each ripple accounts for one second-order filter stage. Filters with even order numbers generate ripples above the 0-dB line, while filters with odd order numbers create ripples below 0 dB.  ...
