The gain-boosting technique improves accuracy of cascoded CMOS circuits without any speed penalty. This is achieved by increasing the effect of the cascode transistor by means of an additional gain-stage, thus increasing the output impedance of the subcircuit. Used in opamp design, this technique ...
