28 Implementation of Multivalued Logic Circuits (MVL), Using Current Mode CMOS circuits
3(ternery) or more logic levels Comparison with binary: Pros: Less number of transistors (smaller area) and less interconnections required to implement same function Faster (if current mode is used) Cons: Static power dissipation Smaller noise margins Level restoration required

29 Implementation of MVL, Using Current Mode CMOS circuits
Gate library for Current Mode combinational logic has been developed. Arithmetic units such as full adder and multiplier circuits has been designed. Presently we are trying to design sequential MVL circuits such as flip flops & counters And, at the same time, trying to optimize and find simpler circuits for the sequential MVL.

30 Design of high frequency, high order active filters using Current Mode CMOS circuits
New CCII circuits with higher frequency bandwidth (above 1GHz), lower input resistance and higher voltage swing, has been developed. Presently we are trying to design high order-high frequency filters, by using these CCII components, for realistic applications Calculating the noise figures and dynamic ranges of the new circuits and see if they are suitable for real applications.
