Abstract

The invention discloses a TSPC trigger with a setting reset function, the trigger is composed of seven PMOS transistors, ten NMOS transistors, two inverters and an NAND gate, and by setting a settingsignal and a reset signal, the trigger has three modes: a common mode, a setting mode and a reset mode. Compared with a traditional static logic D trigger with a setting reset function, the TSPC trigger provided by the invention has the advantages that the working frequency of the trigger is high; and compared with a TSPC trigger only having a setting function and a TSPC trigger only having a resetting function, the trigger has the setting function and the resetting function at the same time, the use flexibility of the TSPC is improved, the structure is simple, and the implementation complexity is low.

Description

technical field [0001] The invention relates to the field of semiconductor integrated circuits, in particular to a true single phase clocked (True Single Phase Clocked, TSPC) flip-flop with a reset function. Background technique [0002] As an indispensable sequential logic structure in standard cells, D flip-flops are widely used in various designs. Traditional static logic D flip-flops with set-reset functions such as figure 1 As shown, it consists of four MOS transistors, five inverters and four NAND gates. The disadvantage of this flip-flop is that it uses a large number of MOS transistors, occupies a large layout area, and has a low operating frequency. TSPC flip-flop adopts dynamic logic and has high working frequency. Based on this, a large number of TSPC flip-flops appear in the prior art. [0003] The invention patent application with publication number CN 109379061A discloses a TSPC flip-flop with setting function, such as figure 2 As shown, it includes: six ...
