摘要:The current mirror is one of the necessary parts in CMOS (Complementary Metal Oxide Semiconductor) analog circuit design. The current mirror can be used as an active element and as a biasing circuit. The circuit structures are supposed to be compatible with low-voltage operating environments to avoid the decrement in system performance caused by the low-voltage low-power designs including reduction of speed and operating current. Therefore, it is required to design the low power analog circuits based on CMOS technology. And for this, the feature size of the CMOS devices has decreased to very small dimensions. The current mirrors have been so modified so that magnitude of incremental output resistance and the accuracy of current-transfer ratio can be improved. Many of the biomedical circuits require large-voltage compliance current sources and current mirrors having high output impedance. Modern Nano-CMOS technologies are bring into being very appropriate to accomplish this objective
