Abstract :
A comparison of three different approaches on the reduction of low frequency noise in single ended CMOS operational amplifiers is made. The particular concepts are the increase of the gare areas, the chopper technique, and the Auto-Zero technique, respectively. Measured data from realized circuits as well as predicted data derived from equations are presented.
