This Article contains a typographical error. In the Results section under subheading ‘Analytical Model, Piecewise Linear System Dynamics and connection to Spectral Algorithms’,

“If the voltage v is normalized to v dd then p(s) = s.”

should read:

“If the voltage v is normalized to v dd then p(s) = g m s.”

In addition, all instances of g i s should be g m s.
