This paper presents the high-output-impedance current-mode multiphase sinusoidal oscillators (MSO) using voltage differencing current conveyor (VDCC)-based lossy integrators, which consist of one VDCC, grounded capacitor, and two resistors. The proposed oscillator can provide an odd-phase even-phase system without use additional amplifier. frequency oscillation (FO) is electronically tuned via ...

This paper presents two transadmittance mode universal filters having single voltage input and multiple current outputs. The filter employs three multiple output current controlled conveyors (MOCCCII) and two grounded capacitors. It can realize low pass, high pass, band pass, notch and all pass responses. As desired, the input voltage signal is inserted at high impedance input terminal and the ...

Compared with the field-effect transistor, the source-gated transistor has a much lower saturation voltage and higher output impedance. These features are investigated using computer modeling for amorphous silicon transistors operated at high currents when source barriers are low. In particular, it is shown that low saturation voltages are maintained at high current and are insensitive to sourc...

The stability margin of an audio power amplifier is reduced by a pole in the loopgain transfer function caused by shunt capacitance in the loudspeaker load. The problem is most severe in amplifiers with output stages that have a high output impedance before feedback. Because MOSFET devices can have an output impedance that is much higher than BJT devices, amplifiers with WFlT output stages are ...

Even though the two-stage Wilkinson N-way power divider is simple to design, realize and test, It has been used with strict restrictions in design and fabrication because it requires a very high impedance microstrip line, i.e., extremely low aspect ratio W/H or very thin line conductor width. To overcome this limitation in realizable characteristic impedance a quarter-wave length impedance tran...

Current mirror (CM) is the basic building block in analog and mixed mode circuit design. For high performance analog circuit applications, the current transfer ratio, output impedance and output swing are the most important parameters to determine the performance of the current mirror. CM’s are important for analog integrated circuits because of their wide use as constant sources or active load...
