Calculating Distortion Levels in Sampled-Data Circuits Using SPICE

This paper presents an analysis technique that can be used to compute the harmonic and intermodulation distortion levels of a sampled-data circuit directly from a SPICE transient analysis. It is useful for analyzing the non-linear behavior of switched-capacitor and switched-current circuits at the transistor level. The approach is valid for all input signal levels, makes no assumption of the underlying non-linearity, and its accuracy is limited only by the numerical accuracy of SPICE.
