WebA current mirror is a circuit where a bias current is set and then copied, or mirrored, to drive a load. In this project, you will construct and test the simple current mirror of Figure 1 with an adjustable bias current set using a potentiometer. Figure 1. Schematic diagram of a BJT current mirror with an adjustable current. WebMar 12, 2007 · Activity points. 1,277. Re: current mirror. Current Mirror. 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.

This current causes the gel to change color, which dims the appearance of the mirror. When there is no more glare to trigger the sensor, the current stops. foamy plansWebAug 19, 2024 · Below is the schematic of the current mirror.
