Diode Based Trimode Multi-Threshold CMOS Technique for Ground Bounce Noise Reduction in Static CMOS Adders
In this paper a high performance diode based trimode Multi-Threshold CMOS (MTCMOS) technique is introduced which minimizes standby leakage current and provides a better way to control the ground bounce noise during sleep to active mode transition using one additional mode i.e. hold mode. Analysis of trimode MTCMOS technique using low power 16-bit full adder has been done for reduction of standby leakage current and ground bounce noise. Further, to evaluate the effectiveness of diode based trimode Multi-Threshold CMOS technique, simulation has been done on low power 16-bit full adder circuit with BPTM 90nm technology at room temperature with supply voltage of 1 V. Diode based trimode Multi-Threshold CMOS technique reduces ground bounce noise by 89.36% and standby leakage current by 19.24% as compared to the standard trimode MTCMOS technique.
