Current mirrors are one of the key elements in Analog circuit design. For high performance analog circuit applications, the accuracy and output impedance are the key parameters for determining the performance of current mirror. Designing the appropriate current mirror topology for the circuit is a matter of tradeoffs between current transfer ratio, power consumption, area on chip, impedance, expandability etc. The paper presents a novel Improved PMOS Wilson current mirror that has excellent characteristics, the result is verified through SPICE simulation on BISIM2 Level 5 parameters.
