How does a current mirror work
WebWith a current mirror. You use a pair of PNP transistors to just mirror the drain current from the sensor, and make the second PNP to just supply a copy of such current to the device receiving it. Sometimes it is awkward to think to use current mirror in the normal PCB with regular components, and yes, it is.

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.
