Current mirrors are core structures for almost all analog mode circuits and are integral part of a signal processing elements like op amps. The performance of analog structures largely depends on their characteristics. In this paper we present some of the current mirror circuits and analyze their performances, so that one can choose a suitable current mirror for a particular application.
