Abstract :
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 nonlinear 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 nonlinearity, and its accuracy is limited only by the numerical accuracy of SPICE
