Abstract

An Interstage Correlated Double Sampling technique is proposed. This new technique avoids the additional thermal noise penalty and the overall feedback factor degradation introduced by the conventional correlated double sampling techniques. In the proposed architecture, a two-stage amplifier is employed and the correlated double sampling is applied to the input of the second gain-stage. The superior noise performance and the gain enhancement of the proposed architecture to the conventional CDS technique is demonstrated in this paper.
