Abstract

PURPOSE:To generate a pulse signal with prescribed pulse width by a small number of constituent elements by providing a frequency dividing circuit wherein frequency dividing stages dividing the frequency of the output of an oscillation source are cascaded. CONSTITUTION:An input from an oscillator 1 is connected via an inverter 2 to the initial stage B1 of a frequency dividing circuit 3 wherein frequency dividing stages B1-Bn dividing the frequency of the input by two are cascaded and also supplied to the frequency dividing stage B1 through an inverter 4. Then, connecting input terminals 13a and 13b of an output circuit 9 to the output of a prescribed frequency dividing stage obtain a pulse signal having a prescribed frequency. Further, the pulse width of the output pulse signal is reduced by a latch circuit 15. A pulse output appearing at the output terminal 21 of the latch circuit 15 is supplied to the input terminal 13a of the output circuit 9, and the Q output of the frequency dividing stage B5 is supplied to the input terminal 13b. Consequently, a pulse signal with prescribed pulse width appears at the output of an NOR circuit 10. This constitution generates the pulse signal having the prescribed pulse width by a small number of constituent elements.
