Abstract
Novel bulk-driven current mirror (CM) and bulk-driven cascode CM are presented in this paper. Bulk-driven technique is employed to overcome a threshold voltage limitation. Proposed circuits operate at 1V power supply. By using a negative feedback, high accuracy input and output transfer characteristic over wide current range is achieved. The proposed circuits are simulated using a 0.18μm CMOS technology. The headroom voltage is 0.11V for the proposed bulk driven CM and 0.16V for the proposed bulk driven cascode CM.
