How current mirror works
Did you know?
WebThe connection is basic to how a current mirror works. The two gates are connected together so that both FETs are driven to the same level. This assumes well-matched FETs, as would be the case with them being next to each other on the same IC. The way the current mirror works is that the desired current is forced D-S thru M1.

A current mirror may be thought of as an adjustable current regulator, the current limit being easily set by a single resistance. It is a rather crude current regulator circuit, but one that finds wide use due because it issimple. Hope that this was helpful. Mar 10, 2007.

While you can practice … can intraocular lenses become cloudyA 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 … Ver mais 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 … Ver mais For small-signal analysis the current mirror can be approximated by its equivalent Norton impedance.
