Metamutator based universal, single input multi output current mode filter

Abstract

The introduction of Add - Differentiate IC, AD-IC, a new integrated circuit, into schemes for realizing single input multiple output current mode filters is the motivation behind this paper. In the circuit structure of this filter with only one active device with a minimal number of transistors and five passive components are being used. Non ideal effects of the design are investigated and simulation results of the application, using TSMC 0.25 mu m process parameters with +/- 1.25 V power supply voltage and the bias VB$$ {V}_B $$ as 0.8 V resulting in 0.99 mW power dissipation for the entire filter, are also presented to confirm the theoretical analysis. With this new design technique, the tunabilities of the angular frequency ( omega 0$$ {\omega}_0 $$) and quality factor ( Q$$ Q $$) can be performed independently.
