Abstract
PURPOSE: To secure the assured automatic clear operation by actuating the time constant circuit which secures the time necessary for the automatic clear operation after the power voltage rises higher than the minimum operation voltage of the electronic circuit and delivering the clear signals during the operation period.
CONSTITUTION: The detection output of voltage detector circuit 1 features the low level for the level under which both power voltage VGG and VDD turn on MISFETQ8 and Q9, thus the low-level clear operation signals being delivered. When both VGG and VDD feature the voltage enough to turn on MISFETQ8 and Q9, the output of circuit 1 becomes the high level turn on MISFETQ13 and then to actuate time constant circuit 2. Then the time necessary for the clear operation is set up by the time constant (C1, Q14), and thus the assured clear operation is ensured under the rise of any power voltage. After this, the output of circuit 2 is applied to FF circuit 3, and the output is inverted to the high level to release the clear operation but with the output kept inverse. Thus, the automatic clear circuit can be applied widely.
