This technique was demonstrated on a GaAs FET by plotting its drain current versus voltage trajectory at 5 GHz.

  • Signal space - an implementation of the harmonic balance approach for microwave nonlinear network analysis

    Harmonic balance is today the most useful approach for nonlinear microwave network analysis. Usually FFT is used to convert the nonlinear elements time waveforms into the frequency domain as part of the harmonic balance process. This approach is straight forward for a single frequency. excitation, but is quite complicated and time consuming for the multi-frequency excitation case. Steer [1] proposed the Generalized Power Series, which enables for a given nonlinearity a direct calculation of the currents spectrum given the voltages spectrum. In this paper we propose a mathematical model termed Signal Space, which is similar to Steer's approach but better suited to implementation for harmonic balance. In [2] we extracted the signal space and made an approximation between the harmonic currents subspaces to enable a treatment of high nonlinearity of elements. Under describing function criteria we use the Signal Space approach to get expressions for oscillator parameters such as oscillation frequency, stability condition, injection locking bandwidth etc. Our results are compatible with Kurakawa's expressions.

Envelope time-domain waveform extraction and correction is applied to the DUT reference plane, preserving vector correction even in modulated environments where ingoing and outgoing signals from the ports of the DUT can be distinguished. This tool is valuable in the analysis of nonlinear devices, the generation of behavioral models and the study of memory effects..

  • Sensitivity analysis of nonlinear circuits using Volterra series

    Volterra series (VS) is frequently used in the analysis of mildly nonlinear circuits. In this approach, nonlinear circuit analysis is converted into the analysis of a series of linear circuits. The main benefit of this approach is that linear circuit analysis is well established and direct frequency domain analysis of a nonlinear circuit becomes possible. In this paper, we present for the first time the sensitivity analysis of mildly nonlinear circuits in the frequency domain as an extension of the VS approach. Sensitivity analysis is useful in comparing the quality of two different designs and in gradient based optimization methods. One example circuit is analyzed and the sensitivity of the output to circuit parameters is given

  • Contactless Measurement of Absolute Voltage Waveforms by a Passive Electric-Field Probe

    This work proposes an improved technique for accurate, contactless measurement of the absolute voltage waveforms of microwave circuits, employing a passive electric-field sensing probe. The proposed technique uses an electromagnetic model of the interaction between the probe and a device under test, to allow the extraction of the coupling capacitance variation versus frequency. Employing these information the measurement accuracy is improved, especially for higher (i.e., harmonic) frequencies, yielding enhanced waveform fidelity. The proposed method is validated on a microstrip line carrying waveforms with rich harmonic content. The accuracy of the proposed technique is benchmarked against a conventional thru-reflect-line (TRL) de-embedding approach by a nonlinear vector network analyzer (NVNA). Measurement results show that the root-mean square (RMS) error can be improved by 3 percentage points (from 8% to 5%) compared to the prior arts over the frequency range from 1 to 5 GHz.

  • Nonlinear dynamical system identification by piecewise-linear system

    An identification method for a nonlinear system using PWL (piecewise-linear) systems is proposed. An adaptive parameter identification scheme with adaptive observers is used. In the adaptive laws, the continuity of the PWL model is taken into account. Since it is assumed that the available data for a given nonlinear system are its input and output time series, this problem setting is practical.<<ETX>>
