<p>PURPOSE:To attain oscillation with simple constitution by allowing a reference voltage source to stop the operation of a discharge current source and allowing an output of a comparator to stop the operation of the reference voltage source. CONSTITUTION:When a voltage of a capacitor 10 is lower than the reference voltage 13, an output of a comparator 14 activates the reference power supply 13 to cut off the discharge current source 12 thereby charging up the capacitor 10. When the voltage of the capacitor 10 reaches a voltage of the power supply 13, the output of the comparator 14 cuts off the power supply 13, the power supply 13 activates the current source 12 to discharge the capacitor 10. The circuit acts as an oscillation circuit by repeating the operations above.</p> |
