ABSTRACT
Power consumption in high performance integrated circuits have been one of the most serious constraints in designs recently. The conditional discharge flip flop(CDFF) belonging to one of the fastest pulse triggered flipflop reduces internal switching activities as that of existing explicit pulse triggered Data close to output flipflop (Ep-DCO). Registers are the main parts for processing information eg: in counters, accumulators etc.,. Implementation of these registers using CDFF can achieve low power consumption and high performance. MTCMOS (multi threshold CMOS) technique saves the leakage power during standby mode operations and hence, enhances the circuit performance for long battery life applications. We find that, using both MTCMOS and conditional discharge technique in flip flop, improves the performance and also consumes low power. In this paper, we simulate CDFF and the proposed MTCMOS CDFF to prove that MTCMOS CDFF is the best among the fastest pulse triggered flipflops. We also implement an application 4 bit shift register using proposed MTCMOS conditional discharge flip flop.
