ABSTRACT:
A single event upset immune latch circuit comprises a first latch having first and second complementary channel inverters respective input nodes and output nodes of which are cross-coupled to one another. First second pairs of (complementary channel) decoupling transistors respectively couple the output nodes of said first and second complementary channel inverters in circuit with first and second voltage supply terminals. (Cross-)coupled with the first latch is a second latch having third and fourth complementary channel inverters, respective input nodes and output nodes of which are cross-coupled to one another. Third and fourth pairs of (complementary channel) decoupling transistors respectively couple the third and fourth complementary channel inverters in circuit with the first and second voltage supply terminals. Respective input nodes of the first and second latches are mutually (cross-)coupled with the gates of the pairs of complementary channel transistors of the first and second latches, so as to bias the gates of the first and second pairs of complementary channel transistors at voltage levels complementary to the voltage levels stored by the inverters to which they are coupled.
