Time varying Volterra series and its application to the distortion analysis of a sampling mixer

We develop the time varying theory of Volterra series, and use the theory in the sampled data domain to solve for harmonic distortion of a passive MOS-based track-and-hold sampling mixer with a finite falling time LO voltage. We also quantify distortion due to sampling error. These results, when combined with the time invariant solution, quantify harmonic distortion and intermodulation of the mixer completely.
