چکیده

This paper proposes a new current mirror layout technique to improve matching characteristics in the presence of parameter gradient. Effects of threshold gradients across a mirror on the matching characteristics of current mirrors are discussed. New and the existing layouts are compared with computer simulations for threshold voltage gradients at all angles across the active area. Results show a significant improvement in matching characteristics of the proposed structures over what is achievable with existing layout techniques.

Gradient sensitivity reduction in current mirrors with non-rectangular layout structures

A new current mirror structure using a nonrectangular dual-drain device with a shared channel to reduce the matching sensitivity to linear parameter gradients is introduced. The new structures are compared with conventional common centroid layouts for threshold voltage gradients at all angles across the active area of a mirror. Results show that in some applications, significant improvement in ...

A Power Efficient Gain Enhancing Technique for Current Mirror

This work introduces a new and simple method for adjusting the gain of current mirror. The major advantage of the proposed architecture is that, unlike the conventional variable gain current mirror, it does not need the change of the biasing current to adjust current gain. Therefore, the power dissipation remains constant in all of the gain settings. In addition, the proposed variable gain curr...

A Broadband Low Power CMOS LNA for 3.1–10.6 GHz UWB Receivers

A new approach for designing an ultra wideband (UWB) CMOS low noise amplifier (LNA) is presented. The aim of this design is to achieve a low noise figure, reasonable power gain and low power consumption in 3.1-10.6 GHz. Also, the figure of merit (FOM) is significantly improved at 180nm technology compared to the other state-of-the-art designs. Improved π-network and T-network are used to obt...

A Novel Technique for Steganography Method Based on Improved Genetic Algorithm Optimization in Spatial Domain

This paper devotes itself to the study of secret message delivery using cover image and introduces a novel steganographic technique based on genetic algorithm to find a near-optimum structure for the pair-wise least-significant-bit (LSB) matching scheme. A survey of the related literatures shows that the LSB matching method developed by Mielikainen, employs a binary function to reduce the numbe...
