Because of installation for local consumers and since it is free of all contaminations, connecting photovoltaic cells to the grid via single-phase inverter is significantly on the rise. In this paper, a new simple current control is proposed for a single-phase grid-connected voltage source inverter. Using the PQ theory and modelling a single-phase system as an unbalanced three-phase system, a m...

This paper includes the study of a known very simple reference current source, having two branches, where the temperature-compensation of the sum of branch currents (the total current) is done. This kind of approach is adequate when the reference must supply current in a charge with grounded or connected to voltage supply end. The first-order thermal compensation of the reference current is ana...

A resistorless CMOS nonbandgap voltage reference, which is compatible with 180nm CMOS Technology is presented in this paper. In order to reduce the temperature nonlinearity in proposed voltage reference, threshold voltage and a proportional to absolutely temperature (PTAT) voltage form the basic linear temperature components, which are achieved by resistorless threshold voltage extractor and di...

Keynote Lecture Large-scale extracellular electrical recordings using various types of multicontact microelectrodes have become a common tool for investigating neural activity at the population level. Here we present results from several projects in our group aimed at elucidating the link between recorded extracellular potentials and the underlying neural activity. We further present several ne...

This paper describes a CMOS voltage reference circuit which occupies small die area and has less than 1.25 V of output voltage. The reference voltage is determined by a resistor ratio, and it is possible to set the reference voltage from zero to near the supply voltage with the same temperature independence as those of Widlar’s and Brokaw’s bandgap voltage references. The temperature-independen...

Phase-control of a magnetron is studied via simulation using a combination of a continuous current source and a modulated current source. The addressable, modulated current source is turned ON and OFF at the magnetron operating frequency in order to control the electron injection and the spoke phase. Prior simulation work using a 2D model of a Rising Sun magnetron showed that the use of 100% mo...

A voltage reference is an essential building block of many analog and digital circuits. The performance of a reference is gauged by the maximum variation in its allowable operating conditions. One of the most important specifications of a reference is its temperature drift. Therefore, special attention should be paid by the designer to the thermal behavior of a voltage reference. In this thesis...
