The advantage of this method involves controlling the flow of current through all the connections – especially those used to measure the voltage. The measurement current flows through one set of connections, usually those that are farthest apart. If these connections are resistive (i.e., the connections are poor) there will be significant voltage drop across them. However, this voltage drop doe...

A new 3-TFT voltage-programmed pixel circuit with an in-pixel current source is presented, which can be largely insensitive to the TFT threshold voltage shift. The fabricated pixel circuit provides OLED current ranging from 25nA to 2.9μA, an on/off ratio of 116 at typical QVGA display timing. Author

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...

The dynamic response of a magnetized collisionless plasma to an externally driven, finite size, sudden switch-on current source across the magnetic field has been studied using a two dimensional hybrid code. It was found that the predominant plasma response was the excitation of whistler waves and the formation of current closure by induced currents in the plasma. The results show that the curr...

Very often electroless electrolytes contribute to wastewater treatment problems. These electrolytes are used in electroless plating processes, which contain a variety of chemicals to meet special surface treatment requirements. Metal salts produce the base material for metal deposition and hypophosphite is delivering the electrons for the metal reduction process – it is basically the internal e...

This manuscript presents the designing and investigative aspects of a low power, wide frequency range, and delay cell based 3 and 5-stage ring oscillator for RF-Ultra-WideBand application. The wide range of frequency is achieved by using two variable voltage sources i.e. control voltage source (Vcntrl) and tail current source (Vtail). A tail current improvement is responsible to control the cha...

Acid and metalliferous drainage (AMD) is broadly accepted to be a major global environmental problem facing the mining industry, requiring expensive management and mitigation. A series of laboratory-scale kinetic leach column (KLC) experiments, using both synthetic and natural mine wastes, were carried out to test the efficacy of our pyrite passivation strategy (developed from previous research...

Photo-voltaic (PV) tied Z-source Neutral-point clamped NPC-MLI (Z-NPC-MLI) is used in solar grid connected applications due to its improved performance related conservative inverters single stage power conversion. Though the Z source adaptation accepted technology, need for appropriate controller meet out grid/standalone requirements becoming necessary. The space vector pulse width modulation (...
