By using an [[RC network]] to add slow [[negative feedback]] to the inverting [[#Schmitt trigger|Schmitt trigger]], a [[relaxation oscillator]] is formed. The feedback through the RC network causes the Schmitt trigger output to [[oscillate]] in an endless symmetric [[Square wave (waveform)|square wave]] (i.e., the Schmitt trigger in this configuration is an [[astable multivibrator]]).
