Title: Flip-flop circuit
Inventor: OBARA KAZUTAKA
IPC: H03K3/037
Filed: 1991-03-27
Abstract: PURPOSE:To realize a flip-flop circuit in a static operation suitable for high circuit integration with low power consumption. CONSTITUTION:The flip-flop circuit is provided with a state monitoring circuit 50 in which the input of a 1st NMOS transistor(TR) 11 whose gate is controlled by a D input is connected to a Q output of an edge trigger D flip-flop and an input of a 2nd NMOS TR 10 whose gate is controlled by a D-input is connected to Q- output and the output of a 1st NMOS TR 11 and the output of a 2nd NMOS TR 10 are connected as its output, and the output of the state monitoring circuit 50 is connected to other input of a clock control circuit 51 composed of a NAND element 12 whose CLK input and input are connected together. When the D input and the Q output are in the same state, the input P1 of the NAND element 12 goes to L and a change in the CLK input is not propagated to the output of the NAND element 12. The power consumption in this case is zero. When the D input and the Q output differ from each other, the input P1 of the NAND element 12 goes to H and the change in the CLK input is propagated to the output of the NAND element 12.
