Abstract

PURPOSE:To establish the voltage comparator circuit less in current consumption and no malfunction with less noise by especially using FET. CONSTITUTION:The input terminal 1 is at greater potential than 2, and when the terminal 7 is at H, the comparator circuit output AB are all zero if the terminal 6 is at H at time ab. At time bd, the terminal 6 is at L and the elements 4, 5 are charged up for the capacitors 11, 14 with the turn of of elements 10, 15. The potential difference at the terminals 1 and 2 brings A to the threshold value quickly and the potential is increased and B is lowered. At time C, CP from the terminal 18 is fed, the potential of B is delivered to FF16 and obtaining the comparison output Q. At time de, the terminal 7 is at L and the voltage between the terminals 3 and 8 with the terminal 7 at L and output Q is held. The power application period is limited to ad and by taking the de longer, the total current consumption can be lowered. This is applied if the terminal 1 is higher than the 2 in potential. The initial potential for A, B is determined by providing the time distance between the time a and b. With this constitution, the malfunction due to the noise before the start of comparison can be avoided and the circuit is operative only during the comparison period and the current consumption can be reduced.
