Title: SYNTHESIS OF LOG-DOMAIN FILTER WITH WELL-DEFINED OPERATING POINT

Abstract: A new systematic approach for the design of n-th order log-domain filters is presented. By eliminating the bias uncertainty, proper working condition is guaranteed for log-domain CMOS realization. This approach is based on the inverse-follow-the-leader-feedback (IFLF) topology and DC negative feedbacks are introduced to define the bias condition. To illustrate the proposed approach, a fourth order low-pass filer is designed and simulated in HSPICE.
