This paper presents, a new current mode four-quadrant CMOS analog multiplier/divider based on dual translinear loops. Compared with the previous works this circuit has a simpler structure resulting in lower power consumption and higher frequency response. Simulation results, performed using HSPICE with 0.25um technology, confirm performance of the proposed circuit.

A novel coupled-line structure is proposed to design dual-band and high-power Gysel power dividers with inherent impedance-transforming functions. Based on traditional even- and odd-mode technique, the analytical design methods in closed-form formula are obtained and the accurate electrical parameters analysis is presented. Due to the usage of coupled-line sections, more design-parameter freedo...

A phase-locked-loop (PLL)-based frequency synthesizer incorporating a phase detector that operates on a windowing technique eliminates the need for a frequency divider. This new loop architecture is applied to generate the 1.573-GHz local oscillator (LO) for a Global Positioning System receiver. The LO circuits in the locked mode consume only 36 mW of the total 115-mW receiver power, as a resul...

This paper presents the design of a novel dual-band unequal Wilkinson power divider. The proposed power divider can operate at arbitrary two frequencies without reactive components. The design and analysis of power divider are presented. The structure of the power divider and the formulas used to determine the design parameters have been given. Closed-form design equations are derived based on ...

A fully integrated dual-mode frequency synthesizer for GSM and Wideband CDMA (WCDMA) is presented. The synthesizer is designed to maximize hardware sharing between the two modes by applying fractional frequency synthesis to GSM mode and integer frequency synthesis to WCDMA mode. The shared components include phase frequency detector (PFD), charge pump (CP), loop filter, integer frequency divide...

This article presents a new current-mode multiplier/divider based on MO-CDTA (Multiple output current conveyor transconductance amplifier). The circuit description is very simple, its construction consists of only one MO-CDTA. Without external passive elements, the proposed circuit is then suitable for IC architecture. The PSpice simulation and experimental results are depicted, and agree well ...
