Abstract

The invention provides a D (D Flip-Flop) trigger based on a TGMS (Transmission Gate Master Slave) structure, The D trigger is suitable for a subthreshold low-voltage working condition and comprises a principal latch and a secondary latch in cascade connection in sequence; the principal latch is used for stably latching and outputting the input value of the D trigger; the secondary latch is used for stably latching and outputting the output value of the principal latch; the principal latch comprises a first transmission gate, a second transmission gate, a first reverser and a second reverser; and the secondary latch comprises a third transmission gate, a fourth transmission gate, a third reverser and a fourth reverser.

Description

technical field [0001] The invention relates to a device in the field of digital integrated circuits, in particular to a D-type flip-flop (D Flip-Flop, DFF for short) circuit that can work normally under sub-threshold low voltage conditions. Background technique [0002] Wireless sensor network (Wireless Sensor Network, referred to as WSN) is currently a research field that has attracted much attention in the world. It integrates sensor technology, embedded computing technology, distributed information processing technology and wireless communication technology. Through a large number of, A network composed of micro-sensor nodes with micro-processing capabilities can coordinate real-time monitoring, perception and collection of information on various environments or monitoring objects in the network coverage area, and then process them. The processed information is sent wirelessly and sent It is transmitted to the user terminal in an ad hoc multi-hop network for use and anal...
