This paper mainly focuses on the research and design of high-speed and low-power FIMC. Based on the analysis of the existing FIMC, an improved FIMC architecture is proposed, which achieves higher conversion speed and lower power consumption by optimizing the Folded Complementary Pulse Width Modulation (F-CPWM) technology.This paper will first introduce the basic concept and working principle of FIMC. Then, the shortcomings of the existing FIMC are analyzed, and an improvement scheme is proposed. Subsequently, detailed circuit design and simulation analysis are carried out for the proposed improvement scheme. Finally, the FIMC prototype circuit is implemented using TSMC 90nm CMOS technology, and experimental verification is carried out.The experimental results show that the designed FIMC can achieve 12-bit conversion at a speed of 1.2GS/s, and the power consumption is only 512mW. This proves that the proposed architecture and optimized algorithm have a significant effect on improving the performance of FIMC.【Keywords】Folded Interpolating Modulus Converter; F-CPWM; High-speed; Low-power; Circuit Design
