For gender-related information, previous studies have shown that children of
preschool age are more likely to remember schema-consistent information
over schema-inconsistent information. In this study, an attempt was made to
boost children's recognition for inconsistent information. In order to do this,
children were presented with pictures of both gender-consistent and...
In Radio Frequency Integrated Circuits (RFIC) or high frequency digital
ICs, there is a demand to probe the internal nodes for testing. The ultra low
capacitance RFIC probe presented in his work is a flexible tool for these
applications. The probe utilizes the coupling between a tungsten needle and the...
Previous studies on low frequency flicker noise in bipolar junction transistors (BJT) are reviewed. The original BJT flicker noise sources are mainly attributed to the fluctuation in base surface recombination and the fluctuation in the mobility or diffusivity of free charge carriers. Our experiments were done to verify a newly...
Substrate switching noise is becoming a concern as integrated circuits get larger and speeds get faster. Mixed-mode integrated circuits are especially affected as the substrate noise interferes with sensitive analog circuits resulting in limited signal to noise ratios. This thesis serves to study the cause of the noise at the...
A comparison and analysis of jitter for five different architectures of ring oscillators using a novel simulation technique developed by Professor Forbes' group is presented. Ring oscillators have become an essential building block in many digital and synchronous communications system due to their integrated nature and are widely used in...
Imperfections in semiconductor materials constitute a rich area for research. The importance of the characterization of these imperfections cannot be understated. Junction spectroscopic techniques provide a unique tool for the study of these imperfections. The test specimens could consist of Schottky barrier, p-n junctions, or MOS structures. Using Schottky barrier...
A negatively biased substrate has several advantages over a grounded substrate in CMOS
technology. The on-chip generation of this negative substrate bias has made chips easier
to use when only a single supply is preferred. This project demonstrates two types of
charge pump circuits used to generate negative voltages not...
