- 1 - ABSTRACT A digital voltage comparator is illustrated including a cross-coupled latch 10 having input nodes 12 and 14. After the input nodes 12 and 14 of the latch 10 have been respectively pre- loaded to the input A and reference E voltage levels during the active state of clock phase ?1' the latch is allowed to arrive at a stable state during the active state of clock phase ?2. Thereafter, when clock phase ?3 is active, the output of the latch 10 is coupled to the input of a single stage shift register 20. The output of the shift register 20 is fed to inverters 22 and 26 and through a voltage divider for preloading the node 14 of the latch 10 during the next active state of clock phase ?1. Ollendick 5
