CMOS symmetrical output SR flip-latch with self-correction function

Abstract

The invention relates to a symmetry output register, which is characterized in that when the discharge of charge branch with changed state turnovers, it only has one transistor to control the state conversation, to accelerate the turnover speed and improve symmetry; and it has abundant circuit, therefore, when two circuits are in hold state, it can automatically recover the soft error caused by radios.

Description

technical field [0001] The technical field of direct application of "CMOS symmetrical output SR latch with self-correction function" is high-performance integrated circuit design. The proposed circuit is a kind of CMOS symmetrical output latch unit with self-correction function for errors caused by noise, cosmic rays, etc. Background technique [0002] As the CMOS integrated circuit manufacturing process gradually enters the nanoscale field, the scale and complexity of integrated circuits are increasing day by day. Soft errors caused by cosmic ray particle bombardment pose a certain threat to the reliability of integrated circuits. Due to the progress of the process, the node capacitance in the CMOS circuit is reduced, so that the total charge required to make a node flip is reduced, which means that the low-energy cosmic ray particles that would not have an impact in the past will now affect circuit poses enough of a threat. In addition, due to the decrease of the power s...

Problems solved by technology

However, this structure is only for the SR latch composed of NAND, and does not provide the circuit structure of the SR latch composed of NOR.

And more importantly, it does not have the ability to self-correct soft errors
