1. IntroductionWith the rapid development of smart IC electronic technology, portable devices have gained popularity in various fields such as consumer electronics and medical applications. In order to provide stable operating voltage for portable devices, efficient and high-quality power management integrated circuits (ICs) play an increasingly important role due to their high efficiency, strong load capacity, and low static current characteristics.

Abstract:In order to solve the problem of limited linearity and frame rate in the large array infrared (IR) readout integrated circuit (ROIC), a high-linearity and high-speed readout method based on adaptive offset compensation and alternating current (AC) enhancement is proposed in this paper. The efficient correlated double sampling (CDS) method in pixels is used to optimize the noise characteristics of the ROIC and output CDS voltage to the column bus.
