![]() ![]() As the name suggests, it copies the flow of current in one active device whereas, in another active device, it maintains the output current stable instead of loading. Some of these circuits may utilize the above two transistors for allowing the performance level to be enhanced. ![]() Generally, the designing of current mirror circuits can be done with two main transistors and even though other devices like FETs also used. The main function of the current mirror is to provide active loads as well as bias currents to circuits and also used to form a more practical current source. The main function of this amplifier is to reverse the direction of the flow of current. Theoretically, a perfect current mirror is an inverting current amplifier. ![]() The circuit is used to copy the flow of current in one active device and controlling the flow of current in another device by maintaining the output current stable instead of loading is known as a current mirror. ![]()
