This article offers a summary of the approaches used in the design of Cascaded-Integrator Comb (CIC) filters, focusing on their implementation in Field Programmable Gate Arrays (FPGAs). Because of its simplicity, computational efficiency, flexibility for high-speed data handling, and features such as anti-aliasing, interpolation, and noise reduction, CIC filters play an essential role in multi rate signal processing. This study examines current research efforts aimed at improving the performance of CIC filters, such as signal integrity, signal-to-noise ratio (SNR), passband droop, and compensation designs. This paper also portrays a comparative analysis of several parameters such as adders, multipliers, registers utilized, and also Adders per output sample (APOS) and minimum attenuation based on various papers that have similar functionalities but vary in methodologies employed, that affect the overall performance while implementing in hardware.
