Low-Voltage, High-Performance Current Mirror Circuit Techniques

A series of current mirror circuit useful for low voltage analog circuit design are addressed to reduce channel length modulation and offering much higher accuracy. Some of the principle building blocks to realize wide swing and regulated cascode current mirror, to achieve low input resistance, are discussed. By combination of a low supply voltage, high performance, current mirror with high output impedance, low input and output voltage is introduced where is well suited for biasing structures.
