There are three main specifications that characterize a current mirror. The first is the transfer ratio (in the case of a current amplifier) or the output current magnitude (in the case of a constant current source CCS). The second is its AC output resistance, which determines how much the output … See more A current mirror is a circuit designed to copy a current through one active device by controlling the current in another active device of a circuit, keeping the output current constant regardless of loading. The current being … See more For small-signal analysis the current mirror can be approximated by its equivalent Norton impedance. In large-signal hand analysis, a current mirror is usually and simply approximated by an ideal current source. However, an ideal current source … See more 1. ^ Keeping the output resistance high means more than keeping the MOSFET in active mode, because the output resistance of real … See more • 4QD tec - Current sources and mirrors Compendium of circuits and descriptions See more Basic idea A bipolar transistor can be used as the simplest current-to-current converter but its transfer ratio would highly depend on temperature variations, β tolerances, etc. To eliminate these undesired disturbances, a … See more • Current source • Widlar current source • Wilson current mirror • Bipolar junction transistor See more WebMay 27, 2024 · 1.
