AN RMS-DC CONVERTER BASED ON THE DYNAMIC TRANSLINEAR PRINCIPLE

The dynamic translinear principle can be regarded as an extension of t he conventional, i.e., static, translinear principle, The dynamic tran slinear principle cannot only be used to realize linear filters, but a lso constitutes an interesting approach to the implementation of nonli near differential equations. In this brief, as an example, a dynamic t ranslinear realization of the nonlinear differential equation describi ng the rms-dc conversion Function is designed, yielding a circuit with a high functional density. Measurement results of a protoype semicust om realization of the rms-dc converter show a good accuracy for crest factors up to ten and a cutoff frequency beyond 5 MHz for all input si gnal levels.
