Current mirror is one of the most important building blocks of analog integrated circuits. For high performance analog circuit applications, accuracy and output impedance are the most important parameters to determine the performance of the current mirror. A new current mirror based upon regulated-gate cascode (RGC) circuit is proposed to provide very high accuracy and high output impedance. A novel feedback gain stage is used to increase the output impedance and the current matching accuracy significantly. The proposed circuit also has output swing similar as traditional two-stage cascode current mirror.
