GENERAL CURRENT-MODE ANALYSIS METHOD FOR TRANSLINEAR FILTERS

Log-domain or translinear filters are regarded as being a promising al ternative in the area of low-voltage filter design. To date, most publ ications have reported on synthesis of translinear filters. Although s ynthesis is more powerful than analysis, it must go together with a ge nerally applicable analysis method in the same domain. In this paper, a general current-mode analysis method is proposed. By using a current -mode approach, we stay close to the existing theory on static transli near circuits, which might be beneficial in developing a general, poss ibly more powerful synthesis method.
