Power Input of High-Speed Rotary Impellers

High-power millimeter-wave rotary joint.

The rotary joint is a useful microwave component that connects a fixed part to a rotatable part. This study systematically analyzes the effect of the discontinuity on the interface of a rotary joint for several waveguide modes. Simulation results indicate that the transmission of the TE(01) mode is independent of the geometry of the joint, and thus is ideal for such application. A rotary joint ...

High Efficient 3-input XOR for Low-Voltage Low-Power High- Speed Applications

A new 3-Input XOR gate based upon the pass transistor design methodology for lowvoltage, low-voltage high-speed applications is proposed. Five existed circuits are compared with the new proposed gate. It is shown that the proposed new circuit has at least 50% improvement in power-delay product than the CPL structure and than the CMOS structure. Moreover, the proposed new circuit could also be o...

High-Speed and Low-Power Flash ADCs Encoder

This paper presents a high-speed, low-power and low area encoder for implementation of flash ADCs. Key technique for design of this encoder is performed by convert the conventional 1-of-N thermometer code to 2-of-M codes (M = ¾ N). The proposed encoder is composed from two-stage; in the first stage, thermometer code are converted to 2-of-M codes by used 2-input AND and 4-i...

Reduced Input Throw and High-speed Driving

The U.S. Army is examining new and evolutionary concepts for military vehicles for their future force. In particular, drive-by-wire technology coupled with non-standard driving control devices have the potential to lead to improved driving performance, reduced Soldier training time, crash prevention, smaller vehicle space claims, and improved vehicle safety in military vehicles. However, severa...
