Nyquist rate converters have traditionally been used for low to moderate resolution data acquisition applications. In this paper, we describe a feedforward residue compensation (FRC) technique to extend the resolution of such converters using an oversampling modulator loop. Closed-form analytical expressions are developed to provide insight into the operation and limits on the resolution of suc...

Dynamic voltage and frequency scaling (DVFS) is a powerful technique to reduce power consumption in a chip multiprocessor (CMP). To support DVFS in the multicore power delivery network, we integrate on-chip switched-capacitor (SC) DC-DC converters that can work with multiple conversion ratios to provide varying levels of Vdd supplies. We study the application of such SC converters in multicore ...

High-performance and low-power are the two main criteria in modern digital design. Level converters are important to transfer low voltage input swing signal among the circuits operating at different voltages to get high voltage output swing signal. Previously feedback level converters suffer from short circuit power and long propagation delay. Multi Vth level converters and multiple supply volt...

| Since the first demonstration of a comparatorbased switched-capacitor circuit, analog-to-digital (A/D) converters based on virtual ground detection have made steady and significant progress. Comparators have been replaced by zero-crossing detectors, leading to the development of zerocrossing based circuits for faster speed and lower power. All facets of performance including the sampling rate...

In today's electric power systems, power electronic converters play an increasingly important role for integration of smart grids, renewable energy resources and energy storage devices. Power converters are key components that physically connect wind power, solar panels, and batteries to the grid. Traditionally, those converters are controlled using standard control mechanisms. However, recent ...

Abstract: In modern distributed energy systems (DES), focus is shifting from the conventional centralized approach towards distributed architectures. However, modeling and analysis of these systems is more complex, as it involves the interface of multiple energy sources with many different type of loads through power electronics converters. The integration of power electronics converters allows...

The trend in ADCs and DACs is toward higher speeds and higher resolutions at reduced power levels. Modern data converters generally operate on ±5V (dual supply) or +5V (single supply). In fact, many new converters operate on a single +3V supply. This trend has created a number of design and applications problems which were much less important in earlier data converters, where ±15V supplies and ...
