In this study the authors introduce a Ka-band front-end to be used for in-band full-duplex (IBFD) communications. The design consists of a Rat-Race coupler to provide self-interference cancellation (SIC), a low noise amplifier (LNA), a power amplifie

In this paper we investigate the lock time behavior of charge pump phase locked loops (CP-PLLs) which employ voltage controlled oscillators (VCOs) with non-linear frequency tuning characteristics. Since non-linear tuning characteristics leads to vari

In this study, the degradation of adjacent channel power ratio (ACPR) performance in personal mobile radio (PMR) systems, which use two-point modulation in their phase locked loops (PLLs) is investigated. First an expression for the widths of charge

In this study we utilize quadrature rules based on double exponential formulas to evaluate strongly singular volume integrals. First it is shown numerically that double exponential formulas generate efficient quadrature rules for weakly singular volu

In this study finite part integrals are utilized for evaluation of hypersingular and nearly-hypersingular surface integrals on curvilinear elements. These integrals are related to the second derivative of the free space Green' function and arise in t

In this study a new frequency hopping scheme which relies on digital up-conversion of baseband data is proposed. Since the frequency of the local oscillator is kept constant and hopping is achieved in the baseband, the time required for the frequency

In this study we develop a numerical method for evaluation of hypersingular surface integrals, which arise in the solution of electric field integral equation (EFIE) via Nystrom method. Due to the divergent contribution of an infinitesimal area aroun

In this study we use large signal closed loop transfer function and complex quality factor to design a low phase noise feedback oscillator. The method offers two major advantages. First it evaluates the closed loop transfer function, which inherently

Solution of surface scattering problems with electric field integral equation (EFIE) requires careful treatment of singularities introduced by the 3D dyadic Green's function when source and observation points are close to each other or coincide. One
