Four-node flip self-recovery latch based on mutual feedback C unit

The invention relates to a four-node flip self-recovery latch based on mutual feedback C units. The four-node flip self-recovery latch comprises an annular storage module and eight transmission gates, the annular storage module consists of sixteen three-input C units, namely a first C unit CE1, a second C unit CE2, a third C unit CE3, a fourth C unit CE4, a fifth C unit CE5, a sixth C unit CE6, a seventh C unit CE7, an eighth C unit CE8, a ninth C unit CE9, a tenth C unit CE10, an eleventh C unit CE11, a twelfth C unit CE12, a thirteenth C unit CE13, a fourteenth C unit CE14, a fifteenth C unit CE15 and a sixteenth C unit CE16; the eight transmission gates comprise a first transmission gate TG1, a second transmission gate TG2, a third transmission gate TG3, a fourth transmission gate TG4, a fifth transmission gate TG5, a sixth transmission gate TG6, a seventh transmission gate TG7 and an eighth transmission gate TG8. The reliability of the latch circuit is improved, four isomorphic variant latches are provide
