TL;DR: The authors derive a simple sufficient condition for the output of a discrete-time, time-invariant bilinear system to be bounded whenever the input signal to the system is bounded by a finite constant.

20 May 2001TL;DR: In this article, the linearization technique with the 2nd harmonic termination can increase IIP/sub 3/ by an amount of 16 dB max. without additional DC power consumption at optimal bias condition.
Abstract: CMOS RF MMIC amplifiers are fabricated with linearization technique using multiple gated transistors. At 900 MHz, double and triple gated amplifiers show 2.5-4.5 dB larger figure of merit (linearity-DC power consumption), which means that only 1/2/spl sim/1/3 of DC power is needed to obtain the same OIP/sub 3/ value. Using Volterra series analysis and harmonic balance simulation, it is shown that the linearization technique with the 2nd harmonic termination can increase IIP/sub 3/ by amount of 16 dB max. without additional DC power consumption at optimal bias condition, which can reduce more than 90% of DC power consumption with the same linearity performance.

TL;DR: In this article, the authors present an analysis of the broadening of the bandwidth of narrowband modulated signals, commonly called spectral regrowth, caused by weak nonlinearities using Volterra methods and operating entirely in the frequency domain.
Abstract: The author presents an analysis of the broadening of the bandwidth of narrowband modulated signals, commonly called spectral regrowth, caused by weak nonlinearities. The analysis uses Volterra methods and operates entirely in the frequency domain. It is applicable to signals having either discrete or continuous spectra.

TL;DR: In this paper, the output frequency behaviors of nonlinear systems can be expressed using a number of one-dimensional functions similar to the approach used in the traditional frequency response analysis of linear systems.

TL;DR: In this article, a parametric system identification approach has been adopted in the VOLTERRA series response structure for parameter estimation of polynomial form nonlinearity, where first and higher order frequency response functions are extracted from the measured response harmonic amplitudes through recursive iteration and relationships between higher order FRFs and first order FRF are then employed to estimate the nonlinear parameters.
