Performance of Asynchronous Queasy Delay Insensitive (QDI) Circuit Templates

Asynchronous Queasy Delay Insensitive (QDI) is the more promising solution for the reducing the effect off power consumption due improvement in the fabrication technology. In literature there were proposed many QDI techniques but Precharged Half Buffer (PCHB), Autonomous Single Validate Half Buffer (ASVHB) and Sense Amplifier Half Buffer (SAHB) are efficient techniques. In this paper author implemented the templates of PCHB, ASVHB and SAHB. Simulation results are verified, and results are compared. From the result it is observed that SAHB will consume the less power and takes the less area for constructing the template when compare to other two methods.
