“…A distortion contribution analysis (DCA) is determined by the total contribution at the output of an analog electronic scheme as the sum of the contribution of distortions of its sub-schemes, reported in work [15]. DCA helps the designer define the actual source of distortion.…”

“…As the general analysis of the reviewed works has revealed, one can note that when analyzing electronic devices represented by equivalent schemes in works [13][14][15][16][17][18], the analysis is usually carried out in the frequency domain for the nonlinearities of the third or even the second order [19,20]. In general, there are very few studies that consider the nonlinear interaction of at least the fifth order [10,11].…”

A methodology has been proposed for estimating the nonlinear effects in radio tracts of receiving and transmitting devices in radio-electronic means of mobile communication systems, based on using the nonlinear transfer functions of the higher-order Volterra series. A procedure has been devised for obtaining the output responses from a nonlinear non-inertia circuit under the harmonious input action using a method for determining the transfer functions of higher orders obtained on the basis of the transfer functions of lower orders. We have derived the analytical expressions for the output responses from a nonlinear system of different orders for three inputs for the case of representing a nonlinear system in the form of a nonlinear non-inertia circuit. The values of the transfer functions of higher orders for a nonlinear non-inertia circuit were determined by using a state variable method. This paper demonstrates the derivation of analytical expressions to calculate a harmonic coefficient based on the second and third harmonics using the nonlinear higher-orders transfer functions of a nonlinear non-inertia circuit. It has been shown that the use of the nonlinear transfer functions to the fifth order inclusive allows a more accurate assessment of nonlinear effects in the form of the harmonious and intermodulation distortions in the radio tracts of radio-electronic means of mobile systems. The outlined technique for determining the nonlinear transfer functions is invariant to the topology of a nonlinear electrical circuit, as well as to the quantity and type of nonlinear elements. Existing estimation procedures of electromagnetic compatibility related to the problems of calculating intermodulation interference can be improved by the introduction of the determined magnitudes of influence products. The proposed methodology makes it possible to evaluate the set of nonlinear effects in the problems related to electromagnetic compatibility in the groups of radio-electronic means with the accuracy required by users

“…For weakly nonlinear fully‐differential G m − C filters of any order, a systematic state‐space approach has been proposed 11 ; the approach results in a fast distortion estimation, but it is developed for this particular circuit family. A distortion contribution analysis by means of the best linear approximation has been recently proposed 12 ; it distinguishes itself from classic distortion methods by adopting a noise‐like analysis, being able to handle complex excitation signals and strong nonlinearities. Its trade‐off is an increased simulation time.…”

Summary This article presents a general, time‐domain method for intermodulation distortion estimation that offers a fast, systematic, and compact formulation. It can be applied to any linear CMOS circuit architecture, with any number of stages, ranging from amplifiers and transconductors to filters, that are characterized by weakly nonlinear behavior. Each CMOS stage of the circuit is modeled as a Gm‐stage with an output current expressed as a more involved function of its input and output voltages, taking into account both powers and cross‐product terms necessary to accurately capture the nonlinear behavior. The proposed method is easily implemented in numerical computing environments like MATLAB or Python and results in a very fast distortion estimation. A number of example topologies simulated in Cadence Spectre illustrate the application of the method and demonstrate its accuracy.

This is done to either determine the full nonlinear response upfront [10]- [14], or to simulate the response of the full circuit when test signals are applied for inspecting certain nonlinearities [15], [16]. For large circuits containing thousands of transistors, such a step suffers from the first and second drawbacks mentioned previously.…”
