Various Current Mirror Topologies: A Survey

In most of the analog and mixed mode circuits, current mirror is the fundamental structure of components included in large electronic systems. High performance of analog structures depends on parameters like output resistance and settling time of current mirrors. High operation speed, small area and less power dissipation are characteristics of circuits built using current mode. In this paper, various current mirror topologies are surveyed based on technology of 90nm. The performance parameters of these technologies like output current, impedance, transconductance and transfer characteristics are also discussed.
