Methods for avoiding the slew-rate limit and the optimal design of hybrid Continuous-Time (CT) Σ∆ modulators with switched-capacitor (SC) DAC are discussed. Limitations on performance due to finite bandwidth and slew-rate of the operational amplifier are analyzed. The use of multi-rate scheme made by a set of time-interleaved SC-DAC moderates the non-linear error caused by the limited slew-rate...

Cascaded multilevel inverter (CMI) topology is prevalent in many applications. However, the CMI requires switches and isolated dc sources, which main drawback of this type inverter. As a result, volume, cost complexity are increased efficiency deteriorated. This paper thus proposes switched-capacitor-based with half-bridge cells only one source. Compared to conventional CMI, proposed uses almos...

This paper studies a design approach that yields robust vibratory MEMS gyroscopes. The design is based on multiple drive-mode resonators with incrementally spaced frequencies, distributed symmetrically around the center of a supporting frame. These resonators are structurally constrained in the tangential direction with respect to the supporting frame. In the presence of an angular rotation rat...

When the number of data used for an identification experiment is small, the data contain transient effects and these effects contribute to the accuracy of the identified model. Consequently, when designing the optimal input signal for an identification experiment in the case of small data set, these transient effects have to be taken into account. In this paper, we present a methodology for opt...

There is an increasing interest in renewable and green energy sources and the integration of Distributed Generation DG into the power grid system. The problem of optimal capacitor allocation in electric distribution systems involves maximizing energy utilization, feeder loss reduction, and power factor correction. The feeder loss can be separated into two parts based on the active and reactive ...
