Guest Editors' Introduction: Advances in 3-D Integrated Circuits, Systems, and CAD Tools - Part 2

h THREE-DIMENSIONAL INTEGRATION HAS been considered one of the most promising breakthrough technologies achieving higher integration density, better performance, lower power consumption, and smaller form factor. Enabling 3-D integration, however, requires innovation and advancement in manufacturing technology, modeling, design methodologies, and optimization algorithms for physical layout, circ...

Nanowatt Range Folding-Interpolating ADC Using Subthreshold Source-Coupled Circuits

A very low power mixed-signal design methodology based on subthreshold sourcecoupled circuits is presented, and a nano-Watt range analog-to-digital converter (ADC) circuit based on folding-interpolating topology is proposed as a complete design example. To reduce the power dissipation to sub-μW level, subthreshold source-coupled circuit family has been developed for both analog and digital part...

Modeling and Analysis of Noise in Integrated Circuits and Systems

In the next 5 to 10 years, GPS will be adding new civil signals to enhance GPS performance for civil users a C/A code signal at the L2 frequency and a very robust wide bandwidth signal at L5 (1176.45 MHz). These new signals, when combined with the existing C/A code signal at the L1 frequency, will certainly provide an enhanced carrier phase ambiguity resolution capability. Surely, others partic...
