Distortion Contribution Analysis of strongly non-linear analog circuits
Book Contribution - Book Chapter Conference Contribution
A Distortion Contribution Analysis (DCA) determines the contributions of each sub-circuit to the total distortion generated by an electronic circuit in a simulation. The results of the DCA allow the designer of the circuit to effectively reduce the distortion.
Recently, a DCA based on the Best Linear Approximation (BLA) was introduced. In this approach, the non-linear sub-circuits are modelled using a linear approximation. The non-linear distortion is represented as an additive noise source. Combining the BLA with the concepts of a noise analysis yields a DCA that works with realistic, modulated excitation signals instead of a one or two-tone excitation.
Up till now, BLA-based DCA has only been applied to weakly non-linear circuits. In this paper, it is extended and applied to a strongly non-linear circuit.
