Abstract
A signal generating circuit for generating a delayed signal in response to a pulsed timing signal with a delay time which is not substantially affected by variations in supply voltage or temperature. A voltage comparator receives a first input from a voltage division point of a voltage dividing circuit coupled across a voltage source. The other input terminal of the comparator is coupled to a RC circuit and to one terminal of a switch, the other terminal of which is connected to the voltage source. The position of the switch is determined by the output of the timing signal source. If desired, a flip-flop having its set input terminal coupled to a periodic pulse source and its reset input terminal coupled to the output of the comparator may have its complementary output used as the timing signal source to the switch, with the normal output of the flip-flop providing the delayed signal. Alternatively, a pair of comparators may be provided, each comparator comparing the RC circuit voltage to a different voltage from different points on the voltage dividing circuit, with the comparator outputs and the switching signal being combined in a logic circuit to obtain the delayed signal.
