Current mirrors are fundamental circuit components in analog and mixed-signal circuits, playing a crucial role in biasing, signal amplification, and active loads. The efficiency of a current mirror is determined by parameters such as output resistance, compliance voltage, power dissipation, and current accuracy. This paper presents a comprehensive study on the design, simulation, and comparative analysis of different current mirror configurations, including simple, Wilson, cascode, and regulated cascode current mirrors. The study evaluates the impact of various semiconductor technologies (180nm, 45nm, and beyond) on these topologies. Simulations are conducted using industry-standard tools like Cadence Virtuoso and HSPICE to compare each design's efficiency, reliability, and power performance. The findings provide in-depth insights into selecting the most suitable current mirror topology for VLSI, RF, and low-power analog design applications.
