Received Jan 5, 2018 Revised Mar 3, 2018 Accepted Mar 20, 2018 This paper proposed three modified Wilkinson power dividers in order to achieve a size reduction and a wide bandwidth. The first structure presented the power divider using compact folded step impedance transmission lines rather than the uniform microstrip line design for operating center frequency of 3 GHz. The second structure sho...

A 0.8-V CMOS Phase-Locked Loop (PLL) has been designed and fabricated by using a 0.13-μm 1p8m CMOS process. In the proposed PLL, the double-positive-feedbacks voltage-controlled oscillator (DPF-VCO) is used to generate current signals for the coupling current-mode injection-locked frequency divider (CCMILFD) and currentinjection current-mode logic (CICML) divider. A short-pulsed-reset phase fre...

Received Feb 14, 2017 Revised Jun 1, 2017 Accepted Aug 11, 2017 Design and simulation for reconfigurable Wilkinson Power Divider (WPD) related to WiMAX application is proposed in this paper. This proposed design relates to dual band WiMAX frequencies at 2.5 GHz and 3.5 GHz. The main purpose of this design is to design a switchable feeding network that can cover the WiMAX standards by reconfigur...

Convolution and Deconvolution is having wide area of application in Digital Signal Processing. Convolution helps to estimate the output of a system with arbitrary input, with knowledge of impulse response of the system. Linear systems characteristics are completely specified by the systems impulse response, as governed by the mathematics of convolution. And with the knowledge of impulse respons...

This paper focuses on designing elliptic curve crypto-accelerators in GF (2m) that are cryptographically scalable and hold some degree of reconfigurability. Previous work in elliptic curve crypto-accelerators focused on implementations using projective coordinate systems for specific field sizes. Their performance, scalar point multiplication per second (kP/s), was determined primarily by the u...

In this paper, a general and easy procedure for designing the symmetrical Wilkinson power divider that achieves equal-power split at N arbitrary frequencies is introduced. Each quarter-wave branch in the conventional Wilkinson divider is replaced by N sections of transmission lines, and the isolation between the output ports is achieved by using N resistors. The design parameters are the charac...

A new method of designing a wideband differentially fed dual-polarized antenna by using three-strip transmission lines (TS-TLs) is presented. power divider composed four TS-TLs first proposed and illustrated its equivalent circuit. Based on the divider, with in-band resonances developed. To enhance out-of-band selectivity, two radiation nulls quasi-elliptic response are obtained utilizing speci...

This paper proposes a two way L and S band Gysel power divider/combiner that uses line to ground resistors. Step by step methods to obtain a wide isolation and transmission bandwidth are presented. A design that uses five resistors is selected and optimized based on Quasi Newton method. Then the Defected Microstrip Structure (DMS) and Defected Ground Structure (DGS) is used to obtain better tra...
