Abstract

A new offset reduction architecture presents, which is called Amplifier Offset Dependent Chopping (AODC). This technique is half reflecting method of random offset in amplifier. The proposed method can reduce 50% of random offset in buffer system. This method is applied in large LCD TV driving system using 0.13um CMOS technology. So we got 40% reduction of output variation.
