    Abstract

    In this paper the stability analysis and design are presented for amplifier-based CMOS analog signal and information processing cells. By analyzing the influence of dominant pole of feedback path on the frequency response of feedback circuits, several design criteria are proposed to keep amplifier-based CMOS analog processing cells stable such as divider and square root. Moreover, several methods to avoid oscillation are discussed for amplifier-based CMOS analog signal and information processing cells. To verify the proposed design, test circuits are fabricated using CMOS 0.6um process and experimental results show that the proposed analysis and design can be used to improve the stability of amplifier-based CMOS analog and information processing cells significantly.
