Abstract
A current generator generates a non-linear output current whose temperature coefficient exhibits a prescribed non-linear-to-quasi-linear curvature when a control voltage range is restricted. This particular current characteristic enables a voltage reference employing the current generator for high-order curvature correction to produce an output voltage whose variation is extremely flat over its industry standard operational temperature range.
