CMOS Current Mode Logic Gates for High-Speed Applications

This paper presents results of a design that uses CMOS current mode logic that can be used to implement the high precision, speed critical elements of the mixed-signal systems. The design is based upon the 0.25-μm CMOS TSMC process. The propagation delays of the new current mode logic are compared to those of equivalent gates implemented in conventional CMOS logic. The results show a propagatio...

High Speed Full Swing Current Mode BiCMOS Logical Operators

In this paper the design of a new high-speed current mode BiCMOS logic circuits isproposed. By altering the threshold detector circuit of the conventional current mode logic circuitsand applying the multiple value logic (MVL) approach the number of transistors in basic logicoperators are significantly reduced and hence a reduction of chip area and power dissipation as wellas an increase in spee...

High Efficiency, High Density, PolyPhase Converters for High Current Applications

As logic systems get larger and more complex, their supply current requirements continue to rise. Systems requiring 100A are fairly common. A high current power supply to meet such requirements usually requires paralleling several power regulators to alleviate the thermal stress on the individual power components. A power supply designer is left with the choice of how to drive these paralleled ...

High Critical Current Density Superconductivity

This project was focused on a basic scientific problem, one that is at the heart of application and development of superconductivity for efficient energy usage. This is improvement in high current density which can only be achieved by learning to pin vortices to the physical structure of its underlying superconducting material. Quantized vortices are the tornado of electrical supercurrents, ubi...
