Applications of Current Mirror Circuit. Hence we get our circuit (MOSFET) out of saturation even if we have designed it for saturation region of operation. Current mirror finds extremely useful in differential amplifier and operational amplifier. Learn more about analog design in this introduction to the current mirror, including how this circuit is implemented in analog ICs. The current mirror is an important analog building block that finds application in such diverse areas as DC biasing and current-mode signal processing. The current mirror is an important analog building block that finds application in such diverse areas as DC biasing and current … The reference current source is created using the current mirror circuit. Hence, changing one reference point also change the current source across different parts of … There are wide applications of Current Mirror Circuit in the field of integrated circuit manufacturing.
So we go for active load using current mirror which is composed of MOSFET and have less process variation. An improved current mirror structure suitable for low voltage analog applications is proposed which has high output impedance (≈5 MΩ), high bandwidth (≈400 MHz), low input (<0.4 V) and output compliance voltages (<0.5 V) and high output current capability (≈500 µA). By using this technique, multiple reference points can be created from a single source. These properties enhance the utility of this type of current mirrors.
