Summary:
A dual-mode pulse-triggered flip-flop design supporting functional versatility is presented. A low-complexity unified logic module, consisting of only five transistors, for dual-mode pulse generation is devised using pass transistor logic (PTL). Potential threshold voltage loss problem is successfully resolved to ensure the signal integrity. Despite the extra logic for dual-mode operations, the circuit complexity of the proposed design is comparable to those of the single mode designs. Simulations in different process corners and switching activities prove the competitive performance of proposed design against various single mode designs.
