A single-stage 24 GHz triple stacked power amplifier using 0.13 μm CMOS process is demonstrated. To Compare with parallel current combining method, series voltage combining method using a stacked amplifier architecture can realize a large output voltage swing from the top transistor without exceeding the transistor breakdown voltage limitations. However, at high frequencies, parasitic capacitan...

A gas permeation model (Coupling Model) has been developed which has the flexibility to be used for different membrane module configurations. The aim of this work is to predict the performance of a single stage gas separation process using membranes and provide a comprehensive description of process parameters like flow rates, composition, stage cut and stream pressure. The significant feature ...

Electrical Engineering (ABSTRACT) The conventional power factor correction circuit has a fixed output voltage. However, in some applications, a PFC circuit with a wide output voltage range is needed. A single phase power factor correction circuit with wide output voltage range is developed in this work. After a comparison of two main power stage candidates (Buck+Boost and Sepic) in terms of eff...

In this paper, Performance of three-level integrated ac–dc converter with Hysteresis Current Control Technique is presented. The proposed converter combines with the operation of the boost power factor correction and the three-level dc–dc converter. By the implementation of Hysteresis Current controller, the switching sequence is under controlled condition and the output voltage of the proposed...

Recently, sustainable supply chain management (SSCM) has become one of the important subjects in the industry and academia. Supplier selection, as a strategic decision, plays a significant role in SSCM. Researchers use different multi-criteria decision making (MCDM) methods to evaluate and select sustainable suppliers. In the previous studies, evaluation is solely based on the desirable feature...

An ultra-low quiescent current low-dropout regulator with small output voltage variations and improved load regulation is presented in this paper. It makes use of dynamically-biased shunt feedback as the buffer stage and the LDO regulator can be stable for all load conditions. The proposed structure also employs a momentarily current-boosting circuit to reduce the output voltage to the normal v...

For my final project, I will be constructing a 70V audio amplifier capable of delivering about 200 watts into a network of transformer coupled loudspeakers. My design utilizes a class G (rail switching) output stage for increased efficiency and lessened cooling requirements. The rest of the amplifier circuit is fairly standard: an input differential pair with negative feedback from the amplifie...
