FinFET current mirror design and evaluation

With trends toward smaller geometries and improved circuit performance continuing, an option being investigated is multigate FETs on SOI substrates. SOI lends itself to SOC systems due to its inherently lower noise and ease of integration of analog, digital, RF and power circuits. A critical analog circuit requirement is accurate current mirroring. Here characteristics of fully depleted FinFET current mirrors are presented. Silicon FinFET current mirrors and their bulk planar counterparts have similar performance and matching: a vital requirement for analog circuitry on this type of material.
