Comment on "Analysis of a Charge-Pump PLL: A New Model" by M. van Paemel
N. V. Kuznetsov, M. V. Yuldashev, R. V. Yuldashev +4
In this short communication we comment on the non-linear mathematical model of CP-PLL introduced by V.Paemel. We reveal and obviate shortcomings in the model.
PLL and Costas loop based carrier recovery circuits for 4QAM: non-linear analysis and simulation
N. V. Kuznetsov, J. Ladvanszky, M. V. Yuldashev +1
Design of stable carrier recovery circuits are used in many applications: wireless digital communication, optical communication, microwave devices and other applications. Quadratur…
Solution of the Gardner problem on the lock-in range of phase-locked loop
N. V. Kuznetsov, G. A. Leonov, M. V. Yuldashev +1
The lock-in frequency and lock-in range concepts were introduced in 1966 by Floyd Gardner to describe the frequency differences of phase-locked loop based circuit for which the loo…
A short survey on QPSK Costas loop mathematical models
N. V. Kuznetsov, O. A. Kuznetsova, G. A. Leonov +2
The Costas loop is a modification of the phase-locked loop circuit, which demodulates data and recovers carrier from the input signal. The Costas loop is essentially a nonlinear co…
Optical Costas loop: pull-in range estimation and hidden oscillations
N. V. Kuznetsov, G. A. Leonov, S. M. Seledzhi +2
In this work we consider a mathematical model of the optical Costas loop. The pull-in range of the model is estimated by analytical and numerical methods. Difficulties of numerical…
Hidden and self-excited attractors in Chua circuit: SPICE simulation and synchronization
M. A. Kiseleva, E. V. Kudryashova, N. V. Kuznetsov +4
Nowadays various chaotic secure communication systems based on synchronization of chaotic circuits are widely studied. To achieve synchronization, the control signal proportional t…
