うにしたパルス発生回路。a switch that is operated on and off; a first switching transistor connected between a power supply and ground; a second switching transistor that is biased into a conductive state due to conduction of the first transistor; first and second differentiating circuits provided between the output of the second transistor and the first transistor, the time constant of the first differentiating circuit being the time constant of the second differentiating circuit; The constant is increased by the current flowing through the first differentiation circuit in response to the operation of the switch.
The current flowing through the second differentiating circuit in response to the conduction of the second transistor causes the first transistor to continue to operate even after the current in the first differentiating circuit disappears. A pulse generation circuit that maintains continuity for a certain period of time.
