Patent number: 11689190Abstract: A true single-phase clock (TSPC) D flip-flop includes four stages. The four stages are serially connected between the input terminal and the output terminal of the TSPC D-type flip-flop. Each stage is selectively equipped with two connecting devices. One of the two connecting devices is a resistive element. The other of the two connecting devices is a short circuit element. When the node between two stages is in the floating state, the voltage change is slowed down by the resistive element. Consequently, the possibility of causing the function failure of the D-type flip-flop is minimized.Type: GrantFiled: October 26, 2022Date of Patent: June 27, 2023Assignee: FARADAY TECHNOLOGY CORPORATIONInventors: Yu-Hao Liu, Sheng-Hua Chen, Cheng-Hsing Chien
