Strange history of an operator o

Abstract

In this paper, it is shown that a description of mildly nonlinear circuits with an operator o introduced in a paper entitled “Distortion in variable-capacitance diodes” by R. G. Meyer and M. L. Stephens is not correct. The error occurring in this article was then replicated in publications of Palumbo and Pennisi on harmonic distortion calculation in integrated CMOS amplifiers, and recently in a paper about “Distortion analysis of a three-terminal MOS-based discrete-time parametric amplifier” by H. Shrimali and S. Chatterjee. In this paper, we derive a correct form of the discussed description.
