Abstract
The present invention discloses a comparator circuit having false-alarm preventing mechanism. An input pair circuit receives a first and a second input voltages from a first and a second input terminals in an the operation state. The input pair circuit and a latch circuit cooperate to perform comparison thereon in the operation state to generate a first and a second output voltages at a first and a second output terminals. A gate and a drain of a first latch transistor are electrically coupled to the first and the second output terminals respectively. A gate and a drain of a second latch transistor are electrically coupled to the second and the first output terminals respectively. A conduction adjusting circuit enhances the conduction of the latch circuit when being triggered. A voltage detection circuit triggers the conduction adjusting circuit when the first and the second output voltages are not within a predetermined range.
