Innovative feedback approach for high-performance low-voltage current mirror

The paper presents an approach to increase the performance in terms of input and output resistance voltage flipped voltage follower (FVF) based current mirror. The proposed technique consists of substituting main output transistor with a network of transistors in a feedback arrangement, designed to improve resistance. Furthermore, a low saturation onset transistor approach is used to improve the performance. approach also helped in reducing the input resistance of the current mirror, which ranges in current range of up to 1 mA is achieved at a minimal current transfer error of 0.38 %. This feedback based current mirror exhibits an output resistance of 29.61 GS2, an input resistance of 30.45 S2, and of 1.464 GHz. The proposed current mirror runs on +/- 0.5 V supply voltage. The robustness of the proposed is evaluated through process corner analysis, temperature mismatch assessment, and Monte-Carlo The performance characteristics of the proposed current mirror have been validated and simulated Cadence Virtuoso and Spectre simulations on 0.18 mu m UMC technology. The validation process pre-layout and post-layout simulation results.
