How does a current mirror work
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 "copied" can be, and sometimes is, a varying signal current. Conceptually, an ideal current mirror is … See more 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 … 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 • Current source • Widlar current source • Wilson current mirror • Bipolar junction transistor • MOSFET See more Basic idea A bipolar transistor can be used as the simplest current-to-current converter but its transfer ratio … See more 1. ^ Keeping the output resistance high means more than keeping the MOSFET in active mode, because the output resistance of real MOSFETs only begins to increase on entry into the active region, then rising to become close to maximum value only when … See more • 4QD tec - Current sources and mirrors Compendium of circuits and descriptions See more WebDec 5, 2024 · Basically, a current mirror can be reasonably accurate with high value emitter resistors and/or precision matched monolithic transistors. But in your case, that won't work. I'll suggest solutions, without current mirror. 1) Wire both LED strings in parallel, with an additional resistor in series with each string.
