Abstract
The Ritz-Galerkin method provides an algebraic approach to the large-signal analysis of exponential-diode detector circuits that avoids the limitations imposed by truncated series approximation. The resulting closed-form algebraic expressions account for the details of operation in both the square-law and linear regions, and are consistent with numerical simulations. Greater-than-square-law slopes are seen under certain conditions, in agreement with numerical simulations. At high input levels the results approach the predictions of a piecewise-linear analysis.<>
