The Field Effect Transistor (FET) is today the basic element of Very Large ScaIe Integrated (VLSI) digital systems. FETs are also used in analog circuits for high frequency (microwave) applications. Different types of FETs are the Metal Oxide Semiconductor Field Effect Transistors (MOSFETs), the MEtal Semiconductor Field Effect Transistors (MESFETs) and the MOdulation Doped Field Effect Transis...

The control of physical properties by external fields is essential in many contemporary technologies. For example, conductance can be controlled by a gate electric field in a field effect transistor, which is a main component of integrated circuits. Optical phenomena induced by an electric field such as electroluminescence and electrochromism are useful for display and other technologies. Contr...

Hole mobility was evaluated by top-contact bottom gate field effect transistor and time resolved microwave conductivity measurements in 2,6-dithienylanthracene and hexyl-substituted 2,6-dithienylanthracene films prepared by spin-coating of their α-diketone precursors followed by photoirradiation, revealing enough high potentials for semiconducting films with charge carrier mobilities of 0.8-0.9...

Asimple analytic method for transistor oscillator design has been developed. This technique defines explicit expressions for optimum values of feedback elements and load through bipolar transistor z-parameters. Such an approach is useful for practical optimization of a series feedback microwave bipolar oscillator. Microwave oscillator design in general represents a complex problem. Depending on...

full adder cell is often placed in the critical path of other circuits. therefore it plays an important role in determining the entire performance of digital system. moreover, portable electronic systems rely on battery and low-power design is another concern. in conclusion it is a vital task to design high-performance and low-power full adder cells. since delay opposes against power consumptio...
