Abstract-Log-domain or translinear filters are regarded as being a promising alternative in the area of low-voltage filter design. To date, most publications have reported on synthesis of translinear filters. Although synthesis is more powerful than analysis, it must go together with a generally applicable analysis method in the same domain. In this paper, a general currentmode analysis method is proposed. By using a current-mode approach, we stay close to the existing theory on static translinear circuits, which might be beneficial in developing a general, possibly more powerful synthesis method.

Abstract-The dynamic translinear principle can be regarded as an extension of the conventional, i.e., static, translinear principle. The dynamic translinear principle cannot only be used to realize linear filters, but also constitutes an interesting approach to the implementation of nonlinear differential equations. In this brief, as an example, a dynamic translinear realization of the nonlinear differential equation describing the rms-dc conversion function is designed, yielding a circuit with a high functional density. Measurement results of a prototype semicustom 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 signal levels.
