Problems solved by technology

[0003] The flip-flop based on the sense amplifier needs to charge the internal nodes of the flip-flop in the pre-charging stage. There are a large number of these nodes, and when SAFF is working, there are still MOS tubes that are always on. Therefore, when SAFF is in use There are problems of large charging power consumption and slow discharge rate

Abstract

The invention provides an amplification circuit, which comprises an isolation module, a sampling module, a charging module and a sensing module, the isolation module is used for isolating a first power supply end and a second power supply end based on an isolation signal, and the sampling module is used for reading input data; the charging module is used for coupling the first output end and the second output end to a first power supply end based on a charging signal, and charging the first output end and the second output end to initial voltage; and the sensing module is used for amplifying the input data based on the amplification signal, the first output end with the initial voltage, the second output end with the initial voltage and the second power supply end, so that the power loss can be reduced, the discharge rate can be improved, and the power delay product can be reduced.

Description

technical field [0001] The present disclosure relates to, but is not limited to, an amplifying circuit. Background technique [0002] Triggers are important components of integrated circuits. Usually, triggers include Transmission Gate Flip-Flop (TGFF), Pulse Triggered Flip Flop (PTFF), and Semi-Dynamic Triggers. Flip-Flop, referred to as: SDFF) and a trigger based on a sense amplifier (SenseAmplifier Flip-Flop, referred to as: SAFF). [0003] In the pre-charging stage of the sense amplifier-based flip-flop, the nodes inside the flip-flop need to be charged. There are a large number of these nodes, and when the SAFF is working, there are MOS transistors that are always on. Therefore, when the SAFF is in use There are problems of large charging power consumption and slow discharging rate. SUMMARY OF THE INVENTION [0004] An embodiment of the present disclosure provides an amplifying circuit, including: [0005] an isolation module, which isolates the first power supply ...
