Abstract :
A technique is described which enhances the high frequency operation of a low voltage folded cascode structure by introducing a zero at the nondominant pole position and providing phase compensation. This technique can be used to develop low voltage operational amplifiers with good gain bandwidth properties and no overhead in power consumption
