A highly sensitive weak current detection circuit for implantable glucose monitoring is presented. The circuit consists of a current splitter, an integrator, a sampling/holding (S/H) circuit, and an 8-bit successive approximation register (SAR) analog-to-digital convertor (ADC). T-switches, source voltage shifting and correlated double sampling (CDS) technology are adopted to reduce the effects...

In this paper, we introduce the Vector Rank M-type L (VRML)-filter to remove impulsive noise from color images and video sequences. The proposed filter uses the Median M-type (MM) and Ansari–Bradley– Siegel–Tukey M-type (AM) estimators into L-filter to provide robustness to proposed filtering scheme. We also introduce the use of impulsive noise detectors to improve the properties of noise suppr...

The content-based access of CAMs makes them of great interest in lookup-based operations. However, the large amounts of parallel comparisons required cause an expensive cost in power dissipation. In this work, we present a novel banked precomputationbased architecture for low-power and storage-demanding applications where the reduction of both dynamic and leakage power consumption is addressed....

A novel low noise trans-impedance amplifier is proposed using low cost 0.18 µm CMOS technology. A resistive-capacitive feedback is used to extend the bandwidth of the amplifier. As the structure is inductor less, it is suitable for low cost integrated optical interconnects. In this paper Improved Particle Swarm Optimization have applied to determine optimal trans-resistance and noise of propose...

This paper describes a technique used to measure oscillator noise sidebands at 94GHz. It is extendible to other frequencies in the millimetre-wave band. Oscillator noise sidebands are particularly significant for Continuous Wave (CW) radars, where the sidebands of the transmit/receive leakage can degrade the system noise figure. Measuring oscillator noise is also a particular challenge at highe...

approved: Gabor C. Temes This thesis describes compensation techniques for cascaded delta-sigma A/D converters (ADCs) and high-performance switched-capacitor (SC) circuits. Various correlated-double-sampling (CDS) techniques are presented to reduce the effects of the nonidealities, such as clock feedthrough, charge injection, opamp input-referred noise and offset, and finite opamp gain, in SC c...
