Current Mirror Circuit Diagram. The current mirror is used to provide bias currents and active loads to circuits. It comprises two transistors one of which has the base and collector connected and the other does not.
It comprises two transistors one of which has the base and collector connected and the other does not. The basic circuit of the transistor current mirror is shown in the diagram below. Well that is how it is supposed to work anyway.
Well that is how it is supposed to work anyway.
The current mirror circuit is simulated using proteus models. The implementation of the current mirror circuit may seem simple but there is a lot going on. To best understand this important circuit building. The simple two transistor implementation of the current mirror is based on the fundamental relationship that two equal size transistors at the same temperature with the same v gs for a mos or v be for a bjt have the same drain or collector current.
