Dynamic translinear nonlinear energy operator

The dynamic translinear principle, in contrast to the conventional, i.e., static, translinear principle, can be used for the realization of frequency dependent transfer functions. Using the dynamic translinear principle we can realize both linear and nonlinear differential equations. This paper presents the dynamic translinear realization of the nonlinear second-order differential equation describing the nonlinear energy operator performing the real time energy detection of analog signals. The expected behavior of the designed nonlinear energy operator is demonstrated by means of simulations.
