AN IMPROVED UWB NON-COPLANAR POWER DIVIDER

A Novel UWB Out-of-Phase Four-Way Power Divider

─ A novel ultra-wideband (UWB) out-ofphase four-way power divider is presented. To achieve a division over a large frequency range, Tjunctions formed by slotlines and microstrip lines are utilized. Based on the transmission-line equivalent-circuit method, we derive the design equations of the proposed power divider. Furthermore, all measured results are in good agreement with the predicted desi...

Non-uniform Transmission Line Ultra-wideband Wilkinson Power Divider

We propose a technique with clear guidelines to design a compact planar Wilkinson power divider (WPD) for ultra-wideband (UWB) applications. The design procedure is accomplished by replacing the uniform transmission lines in each arm of the conventional power divider with varying-impedance profiles governed by a truncated Fourier series. Such non-uniform transmission lines (NTLs) are obtained t...

Low-power radix-8 divider

This work describes the design of a double-precision radix-8 divider. Low-power techniques are applied in the design of the unit, and energy-delay tradeoffs considered. The energy dissipation in the divider can be reduced by up to 70% with respect to a standard implementation not optimized for energy, without penalizing the latency. The radix-8 divider is compared with one obtained by overlappi...

An Improved Current-Mode Squarer/Divider Circuit for Automotive Applications

A current-mode squarer/divider circuit with a novel translinear cell is presented for automotive applications. The proposed circuit technique increases the accuracy of the squarer/divider function with better input dynamic range and temperature insensitivity. Simulation results show that the variation of the output current is within ±0.2% over the temperature range from −40◦C to 140◦C. key word...
