Title:
垂直ランプ波発生回路
Document Type and Number:
Japanese Patent JP4592181
Kind Code:
B2
Abstract:
The invention includes: a capacitor 11 for generating ramp wave; a constant current source 10 for supplying constant current to the capacitor 11 for generating ramp wave; voltage fixing means for charging the capacitor 11 for generating ramp wave and for fixing a terminal of the capacitor 11 by force to a designated reference voltage Vref; and a counter circuit 15 enabling to output control signal having pulse width corresponding to desired waiting time, and that terminal voltage 17 of capacitor 11 for generating ramp wave is fixed to reference voltage while waiting time set by the counting circuit 15.
