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
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.
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.
