A novel ultra-high compliance, low power, very accurate and high output impedance current output stage (COS) with extremely high output current drive capability is proposed in this paper. The principle of operation of this unique structure is discussed, its most important formulas are derived and its outstanding performance is verified by HSPICE simulation in TSMC 0.18µm CMOS, BSIM3, and Level4...

In this paper a multiple output second-generation current conveyor (MOCCII) is presented. The main advantage of the proposed general circuit architecture over a typical structure, well known in the literature, is the use of a high passband multiple output current amplifier block instead of cascaded current mirrors. It gives similar frequency responses for all the outputs of the current conveyor...

In this paper, a Multivariate-Multistage Quality Control (MVMSQC) procedure is investigated. In this procedure discriminate analysis, linear regression and control chart theory are combined to control the means of correlated characteristics of a process, which involves several serial stages. Furthermore, the quality of the output at each stage depends on the output of the previous stage as well...

A novel CMOS operational transconductance amplifier (OTA) is presented, using a fully differential singlestage core OTA as input stage and a differential to single current converter as output stage, each biased at a separate current level. A large gain-bandwidth (GBW) product (2.7 MHz) and a high slew-rate (5 V//.LS) can be obtained by applying a large bias current to the core OTA. Due to the c...

A multi-output second generation current conveyor (MOCCII), that can be used to realized first, second and third generations current conveyors, is proposed. The MOCCII consists of a CMOS differential stage for the voltage input, push-pull stage and the improved cascode current mirrors for the current output. Feedback techniques are proposed in order to provide a voltage gain of 0.991, a current...

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 ...

This paper proposes a new single phase transformerless Photovoltaic (PV) inverter for grid connected systems. It consists of six power switches, two diodes, one capacitor and filter at the output stage. The neutral of the grid is directly connected to the negative terminal of the source. This results in constant common mode voltage and zero leakage current. Model Predictive Controller (MPC) tec...
