<p>PURPOSE:To execute the pulse output of an arbitrary pulse width by providing a latch circuit to be set by a pulse input and to be reset by a reset pulse from a charging and discharging circuit. CONSTITUTION:A latch circuit 1 is set by the input pulse and the rising (falling) of the pulse is generated by the output. The input pulse is simultaneously supplied to a charging and discharging circuit 2 as well and charging operation, discharging operation or operation to couple those operation is executed. Then, the output level is changed according to the respective operation. Since the output level causes the threshold voltages of the R terminal of the latch circuit 1 to cross, reset operation is executed in the latch circuit 1 and the output pulse rises (falls). Thus, the width of the output pulse is determined by the charging and discharging characteristic of the charging and discharging circuit 2. Thus, the output pulse of the arbitrary pulse width can be generated.</p> |
