Current-Mode Filters Advanced Synthesis Methods, Based on Intermediate Transfer Function Algorithm

摘要

In this paper are presented two current mode techniques for low-voltage, continuous-time, analogue filter implementation. The first presented technique is adequate for very low power application and is based on a translinear approach. The second presented technique is adequate for high frequency application. In the paper, firstly, the state-space description and the used synthesis techniques of current-mode filters are presented. Then the two different current-mode integrators are presented and analyzed. Finally, as a test vehicle for the proposed techniques, two low voltage, third order, continuous-time filters, for low power applications structure implementation are described and analyzed.
