Abstract :
A logic design style known as phase difference-based logic (PDBL) has several benefits with respect to security and testing. An existing design method for PDBL circuits has so far been lacking an important component, a register. In this paper, we present the design of a speed independent PDBL register and a timed PDBL register, which can be used in asynchronous or synchronous circuits. Comparisons are presented in terms of speed, size, and power consumption.
