The formalized approach for periodic distortion analysis is presented. The computational method is based on exploitation of the properties of the simplified Newton iterative process to solve nonlinear problems in functional space. The numerical scheme of periodic distortion analysis is described. Unlike Volterra series this technique doesn’t require computation of the second and third derivatives of device models. The special-purpose mode for the periodic distortion analysis of RF circuits is based on the simulation in the frequency domain in the framework of the harmonic balance method.

It is not a trivial task to develop an effective overhead power line short circuit sensor while being restricted on weight, dimensions, power consumption, and the relative position of the sensor and the power line wire. Traditionally, a current transformer similar to a Rogowski coil is used as a sensor, followed up by either a ...

The article introduces the theoretical foundations of the modern method of storing, transmitting and processing signals: digital processing. It’s a way to use relatively small number of values instead of continuous real signal.
For example, when transmitting information in telephony, speech is concentrated in the bandwidth up to 4 kHz. But we need doubled frequency 8 ...

We theoretically study the phase dynamics in Josephson junctions, which maps onto the oscillatory motion of a pointlike particle in the washboard potential. Under appropriate driving and damping conditions, the Josephson phase undergoes intriguing bistable dynamics near a saddle point in the quasienergy landscape. The bifurcation mechanism plays a critical role in superconducting quantum circuits ...

This paper presents a new integration technique for time-domain simulation of nonlinear electronic circuits. The new technique exploits A-stable single-step integration methods of order 1 up to 4 obtained by applying the Obreshkov formula to charge oriented circuit equations. The predictor-corrector algorithm exploited in the transient analysis for solving the initial value problem is described. ...

The application of conventional transient analysis to find the periodic steady-state solution often results in a long simulation time and hence special purpose means are needed. Unlike the transient analysis the periodic steady-state analysis solves a periodic boundary-value problem. The shooting-Newton method transforms the solution of the periodic boundary-value problem to the solution of sequence ...

One of the promising directions in Low Power researches is associated with ferroelectric materials whose effectiveness is based on the existence of two stable states and on the negative differential capacitance in charge-voltage characteristics. The advantages are usually exercised in chains comprising both ferroelectric and traditional nonlinear capacitances (e.g. MOSFET gate) which can contain floating ...
